Question

Four cubes each of 12cm are joined together.find the surface area of the cuboid so formed . Is the surface area equal to the surface areas of the four separated cubes?

Answer 1

surface are of cuboid = 2 (lb + bh + lh)
=2( (12 ×48) + (12 ×12)+ (12×48) )
$48 \times 12 = 576 \\ 12 \times 12 = 144 \\ 48 \times 12 = 576 \\ 576 + 576 + 144 = 1296 \\ 1296 \times 2 = 2592$
= 2592 Sq. cm
