1.	Two cubes each of volume 8 cm3 are joined end to end, then what is the surface area of resulting cuboid.
Answer» Side of the cube, a = 3√8 = 2 cm Now, the length l of cuboid = 4 cm breadth, b = 2 cm height, h = 2 cm Surface area of cuboid = 2(l × b + b × h + h × l) = 2(4 × 2 + 2 × 2 + 2 × 4) = 2 × 20 = 40 cm²

Two cubes each of volume 8 cm3 are joined end to end, then what is the surface area of resulting cuboid.

Answer»

Side of the cube, a = 3√8 = 2 cm

Now, the length l of cuboid = 4 cm

breadth, b = 2 cm

height, h = 2 cm

Surface area of cuboid

= 2(l × b + b × h + h × l)

= 2(4 × 2 + 2 × 2 + 2 × 4)

= 2 × 20 = 40 cm²
