1. 2 cubes each of volume 64
are joined end to end. Find the surface area of the resulting cuboid.
Solution:
let
be length of each cube
Volume of each cube
=4 cm
If, we join 2 cubes each having side equal to 4 cm, we get a cuboid
Length of cuboid= L=8 cm
Height of cuboid=H=4 cm
Breadth of cuboid=B=4 cm
We know that Surface Area of Cuboid
