QUESTION
 

The perimeter of one face of a wooden cube is 20 cm. Find its weight if large 1cm^3 of wood weighs 8.25 g/cc.

EXPLANATION
Explain TypeExplanation Content
Text

Given, perimeter = 20cm

4a = 20cm

a = 5.

Volume = large a^3= large 125cm^3

Given, density = large 8.25g/cc

We know that Mass = density * volume

= 8.25 * 125 = 1031.25g (or) = 1.031 kg.
