Question

The volume of a cuboid is 70cm³.

The length is 2cm and the width is 7cm.
Work out the height of the cuboid.

Answer 1

length=2cm

breath=7cm

height=?

volume=70cm³

Now,

Volume of cuboid =L×b×h

or,. 70cm³=2×7×h

or,. 70 cm³=14 ×h

or,. 70cm³=h

_____

14

therefore, h = 5 cm

Answer 2

Answer: h=5 cm

Explanation:

`\displaystyle\\V_(cuboid)=lwh,\\\\l - the\ lenth,\ w\ -\ the\ width,\ h\ -\ height\\\\Divide \ both\ parts\ of\ the \ equation\ by\ lw:\\\\h=(V_(cuboid))/(lw) \\\\h=(70)/(2*7) \\\\h=(2*5*7)/(2*7) \\\\h=5 cm`
