Question

Find the vol of this prism

Answer 1

V = 396 cm³

Explanation:

the volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular face and h the height of prism )

A =
`(1)/(2)` bh ( b is base and h perpendicular height )

here b = 9, h = 8 , then

A =
`(1)/(2)` × 9 × 8 = 4.5 × 8 = 36 cm² , so

V = 36 × 11 = 396 cm³
