Question

4. Two cubes each of 8 cm edge-are joined end
to end. Find the total surface area of the
cuboid so formed.​

Answer 1

Step-by-step explanation:

Length (l) = 8+8 = 16cm

Breadth (b) = 8cm

Height (h) = 8cm

Area of cuboid = 2(lb+bh+lh)

                         = 2{(16×8)(8×8)(16×8)

                         = 2(128+64+128)

                         = 2(320)

                         = 640 cm^2
