The volume (in m3) of a cuboidal tank, whose dimensions are given as 23 m × 23…

Concept: The volume of a cuboid is the product of its three dimensions — length, breadth, and height: V = l × b × h (all three measured in the same unit, so the volume comes out in cubic units of that measure).

Application: Here the tank has l = 23 m, b = 23 m and h = 9 m. Substituting into the formula and working step by step:

1. Multiply the length and breadth first: 23 × 23 = 529.

2. Multiply this product by the height: 529 × 9 = 4761.

3. So the volume of the tank is 4761 m3.

Cross-check: Multiplying the same three numbers in a different order gives the same total: 23 × 9 = 207, and 207 × 23 = 4761 — confirming the volume is 4761 m3.
