Question

Two cubes each of side 4 cm are joined end-to-end . Find the total surface area and volume of the
resulting cuboid

Answer 1

two cubes are joined end to end

means

breadth=4cm

height=4cm.

length= 4cm + 4cm 8cm

AREA OF CUBOID = 2(l x b + l x h + b x h)

                               = 2((8×4) + (4×4) + (4×8))

                               = 2(80)

                               = 160$cm^{2}$
