A rectangular wooden box with a bottom area of 3.6 square meters and a height of 1.8 meters. If each cubic meter can hold 5.2 kilograms of wood, then the rectangular wooden box can hold wood What's the first kilogram?

You can first calculate the volume of the cuboid, and then calculate the weight of the wood, that's it——
3.6 × 1.8 × 5.2 = 33.696 (kg)

Dig a rectangular water storage tank with a length of 5m, a width of 3M and a depth of 2.5m. What is the floor area of this tank?

Dig a cuboid reservoir of 5m long, 3M wide and 2.5m deep, which covers an area of (15m & # 178;)
5x3=15

There are two reservoirs. The first one is 6m long, 5m wide and 3M deep. The second one is 5m long, 3M wide and 3M deep. At present, the first one is full of water,
The second one is completely empty. If you want to pump some water from the first pool to the second pool, if they have the same water depth, what is the water depth of the two pools?

Let the water depth be X
Then 6 * 5 * x + 5 * 3 * x = 6 * 5 * 3
The solution is x = 2

There is a 3 m long, 2 m wide and 1.5 m deep reservoir. It takes 30 minutes to fill the reservoir with water from a water pipe. What is the water injection rate of the water pipe per minute?

Use a water pipe to inject water into a pool 5.6 meters long, 3 meters wide and 1.5 meters deep. If the water pipe injects 700 liters per minute, how many minutes will it take to fill the empty pool?

5.6 × 3 × 1.5 = 25.2 (cubic meter) = 25200 liters; 25200 △ 700 = 36 (minutes); a: it takes 36 minutes to fill the empty pool

Use a water pipe to inject water into a pool of 5.6 meters long, 3 meters wide and 1.5 meters deep. If 350 liters of water are injected per minute, how many minutes will it take to fill the pool
Full of water?

Volume = 5.6 × 3 × 1.5 = 25.2 cubic meters = 25200 liters
Time = 25200 △ 350 = 72 minutes

Use a water pipe to inject water into an empty pool of 7.2m long, 4.5m wide and 1m deep. If the water pipe injects 810l water every minute, how long does it take to fill it up?

Details are as follows:
The volume of the pool is: 7.2x4.5x1 = 32.4 (M & # 179;)
32.4m³=32.4x1000L
Time required: 32.4x1000 △ 810 = 40 (minutes)
A: it takes 40 minutes to fill up

Use a water pipe to inject water into a pool 5.6 meters long, 3 meters wide and 1.5 meters deep. If the water pipe injects 700 liters per minute, how many minutes will it take to fill the empty pool?

5.6 × 3 × 1.5 = 25.2 (cubic meter) = 25200 liters; 25200 △ 700 = 36 (minutes); a: it takes 36 minutes to fill the empty pool

A cuboid water tank, 8 decimeters wide, water depth 4. Put a stone, then the water surface rises to 6 decimeters; how much is the volume of this stone? Urgent, have to hand it in tomorrow!

Volume of stone = 10 × 8 × (6-4.5) = 120 cubic decimeter

A cuboid glass container is 0.5 meters long, 30 cm wide and 10 cm deep. Put a stone in the water and raise it by 1 cm to find the volume of the stone

0.5m=50cm
50*30*1=1500CM3
The volume of the stone is 1500 cm3

A rectangular wooden box with a bottom area of 3.6 square meters and a height of 1.8 meters. If each cubic meter can hold 5.2 kilograms of wood, then the rectangular wooden box can hold wood What's the first kilogram?
