Help please with workings of possible

Answer 1

V = x³ + 10x² cm³

Explanation:

The volume (V) of the triangular prism is calculated using the formula

V = area of triangular face × length

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

here b = 2x and h = x, thus

A =
`(1)/(2)` × 2x × x =
`(1)/(2)` × 2x² = x²

length = x + 10, hence

V = x²(x + 10) = x³ + 10x²
