1. 2 cubes each of volume 64 are joined end to end. Find the surface area of the resulting cuboid.
let be length of each cube
Volume of each cube
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
