Question

The prism shown has a volume of 35 cm.

Work out h, the height of the triangular cross section.
h
7 cm
4 cm

Answer 1

Height = 2.5cm

Explanation:

Volume = Base(b) x Height(h) x Length(l) / 2

Substitute the information that you have into the equation

Volume = 4 x Height(h) x 7 / 2

Height = 4x7 / 2

= 14cm

35 / 14

= 2.5cm

Answer 2

the height is 2.5 cm

Explanation:

The computation of the height of the triangular section is shown below:

As we know that

Volume = One-half × base × height

35 = One-half × 4 × height × 7

So, the height is 2.5 cm
