Dig a cuboid reservoir, 15 meters long, 8 meters wide and 2.5 meters deep. How many cubic meters can this reservoir store at most?

Dig a cuboid reservoir, 15 meters long, 8 meters wide and 2.5 meters deep. How many cubic meters can this reservoir store at most?

15×8×2.5=300m3

A cylindrical reservoir, the bottom circumference is 25.12 meters, the depth is 2.4 meters, and the water surface is 0.9 meters above the ground. How many tons of water is stored in the reservoir? (1 cubic meter of water weighs 1 ton)

3.14 × (25.12 ﹣ 3.14 ﹣ 2) 2 × (2.4-0.9) × 1, = 3.14 × 16 × 1.5, = 75.36 tons; answer: this reservoir can store 75.36 tons

The perimeter of the bottom of a cube reservoir is 92m. How many tons can it store? A cubic meter of water weighs 1 ton

Hello
Side length of bottom surface = 92 △ 4 = 23 (m)
Volume = 23 × 23 × 23 = 12167 (M3)
Storage weight = 12167 × 1 = 12167 (T)
