Question

Find the volume of the solid. *
7)

Answer 1

B

Explanation:

The volume (V) is calculated as

V = area of triangular face × depth

Area of triangle =
`(1)/(2)` bh ( b is the base and h the height )

Here b = 3 and h = 4 , then

A =
`(1)/(2)` × 3 × 4 = 6 Km²

Now depth = 2, thus

V = 6 × 2 = 12 Km³ → B
