An overhead tank is 2.5 m long, 1.6 m wide and 1.2 m deep. Water stands in it to a depth of only 0.9 m. How many litres of water are in the tank? (1 m³ = 1000 L)

Question

Accepted Answer

3600 L. Use the WATER depth, not the tank depth: V = 2.5 × 1.6 × 0.9 = 3.6 m³ = 3.6 × 1000 = 3600 L. Trap 4800 L: using the full depth 1.2 m, which assumes the tank is full. Trap 3.6 L: forgetting the m³ → L conversion. Trap 360 L: multiplying by 100 instead of 1000.

An overhead tank is 2.5 m long, 1.6 m wide and 1.2 m deep. Water stands in it to a depth of only 0.9 m. How many litres of water are in the tank? $(1 m^{3} = 1000$ L)
