Question

2 cubes each of volume 64cmcube are joined end to end.find the surface area of the resulting cuboid​

Answer 1

Answer:

when you join two cubes 4cm edge to edge one of the dimensions

becomes 8 cm depending upon which ends you join.

The surface area of a cuboid is 2(lb+bh+lh)

Therefore the surface area is 2(4×4+4×8+4×8)

=2(16+32+32)

=2(80)

=160

Hope it will help you ☺️
