Question

The volume of this prism is 180mm³.

The depth of the prism is 12mm.
Work out area of the cross-section.

Answer 1

A = 15 mm²

Explanation:

the volume (V) of a prism is calculated as

V = Ah ( A is the cross section and h the depth )

here h = 12 and V = 180 , then

A × 12 = 180 ( divide both sides by 12 )

A = 15 mm²
