1、50*35+（50*2*+35*2）*2
=1750+540
=2290 (M2)
2. (50 + 35) * 2 = 170 (m)
3. 50 * 35 * 1.5 = 2625 (M3)

A cuboid swimming pool is built in the experimental middle school. It is 60 meters long, 25 meters wide and 2 meters deep. A layer of cement is applied on the bottom and inner wall of the swimming pool. How many square meters is your area?

60*25+60*2*2+25*2*2
=1500+240+100
=1840 (M2)

A cuboid swimming pool is built in the experimental middle school, which is 60 meters long, 25 meters wide and 2 meters deep. A layer of cement is applied to the bottom and inner wall of the swimming pool. How many square meters is the area of cement applied?

Long + wide + bottom
2 * 60 * 2 + 2 * 25 * 2 + 60 * 25 = 240 + 100 + 1500 = 1840 square meters

A swimming pool is 50 meters long and 25 meters wide, with an average depth of 2.5 meters. The walls and bottom need to be plastered with a layer of cement. If 6 kg of cement is needed per square meter, how many kg of cement is needed?

(50 × 25 + 50 × 2.5 + 25 × 2.5) × 2-50 × 25 = (1250 + 125 + 62.5) × 2-1250 = 1437.5 × 2-1250 = 2875-1250 = 1625 (M2) 1625 × 6 = 9750 (kg) a: 9750 kg of cement is required

A cuboid swimming pool, 50 meters long, 25 meters wide and 3 meters deep,
How many square meters of cement area? How many tons of water can the swimming pool hold at most? (1 m and 179; water weighs 1 ton.) ((please give reasons))) urgent

Area of plastering cement = 50 × 25 + 50 × 3 × 2 + 25 × 3 × 2 = 1700 square meters
This swimming pool can hold water up to 50 × 25 × 3 = 3750 cubic meters = 3750 tons

A swimming pool is 50 meters in length, 25 meters in width and 2 meters in average depth. Each surface of the pool should be plastered with a layer of cement. How many square meters is the area of plastering cement? Please explain the basic principle and its formula. Thank you

Touching cement means calculating the surface area
And the swimming pool is regarded as a cuboid without cover
It is 50m long, 25m wide and 2m high
So the surface area of this cuboid is equal to
50*25+2（25*2+50*2）=1550
So the area that needs to touch cement is 1550 square meters
If you don't understand,

A rectangular swimming pool is 20 meters long, 15 meters wide and 2 meters deep. Now it is necessary to cement its surroundings and the ground,
How many kilos of cement will be used? Then put water into the pool. The water surface is 20 cm away from the top of the swimming pool. How many cubic meters of water is there in the pool?

20 * 15 + 20 * 2 * 2 + 15 * 2 * 2 = 440 square meters
A total of 440 / 5 * 3 = 264 kg of cement will be used
20 cm = 0.2 M
Water in the pool 20 * 15 * (2-0.2) = 540 M3

A cuboid swimming pool is 120 meters long, 80 meters wide and 3 meters deep. The walls and bottom of the pool are plastered with cement. The cement is 5 kg per square meter. How many tons of cement do you need
solve

120×3×2+80×3×2+120×80
=720+480+9600
=10800 (M2)
10800 × 5 = 54000 (kg) = 54 (T)
A: a total of 54 tons of cement are needed
The team will answer the questions for you

A swimming pool is 48 meters long, 30 meters wide and 2 meters deep. The walls and floor of the swimming pool should be plastered with a layer of cement, which is calculated as 2 kg of cement per square meter,
How many kilos of cement do you need?

S = L * W + L * h * 2 + W * h * 2
=48*30+48*2*2+30*2*2
=1440+192+120
=1752 (M2)
1752*2=3504（kg）

A swimming pool is 50 meters long, 30 meters wide and 2.5 meters deep. The walls and bottom of the pool are plastered with a layer of cement. If 4 kg of cement is used per square meter, how many kg of cement is required for the swimming pool? What is the floor area of the swimming pool? If the water depth of the pool is 2 meters, how many tons of water is loaded in the swimming pool?

(50x2, 5x2 + 30 × 2, 5 × 2) X4 = cement used
