Question

A metallic cuboid measuring 16cm by 8 cm by 4cm was melted.The material was used to make a cube . What is the length of the cube

Answer 1

Answer:

Step-by-step explanation:

The volume of the metal cuboid = length x width x height = 16 x 8 x 3 = 16 x 24 = 384 cm^3

If this same cuboid is going to be reshaped, then

The  volume of the cuboid = The volume of the cube

Therefore,

l^3 = 384

l = $\sqrt[3]{384}$

l = 7.268..

l = 7.27cm ( 2dp)

Hope this helps.
