Answer 2

The answer to your question is letter A) 144.2 cm³

Explanation:

Formula

Volume = Area (base) x height

Process

1.- Find the area of the base (triangle)

Area =
`(1)/(2) base x height`

base = 4

height = 7

Area =
`(1)/(2) 4 x 7`

Area = 14 cm²

2.- Find the volume

Substitution

Volume = 14 x 10.3

Volume = 144.2 cm³
