Answer:
Height of the tank is 1.5m
Step-by-step explanation:
Given
Shape: Cuboid
Base Dimension = 2.5m by 2m
Volume = 7500 litres
Required
Determine the height of the tank
First, the area of the base has to be calculated;
Next is to calculate the height using volume formula;
Recall that Volume = 7500L [Convert to m³]
So;
Hence;
Substitute 7.5m³ for Volume and 5.0m² for Area in the following formula
Divide both sides by 5.0m²
<em>Hence, the height of the tank is 1.5m</em>
