1.	2 cubes each of volume 64cm3 are joined end to end.find the surface area of the resulting cuboid.
Answer» volume of cube = 64 cm\xa03So, side of cube = 4 cm\xa0When two cubes are joined end to end , their length = 8 cm , breadth = 4 cm and height = 4 cmSo surface area of cuboid = 2(lb+ bh + lh)surface area = 2(84+44+84)surface area = 2(32+16+32)surface area = 2(80)surface area = 160 cm\xa02 160cm3
