Question

two cubes each of volume 8 cm cube are joined end to end ,then what is surface area resulting cuboid .

Answer 1

Side of the cube, a = $\bf\huge\sqrt[3]{8}$  = 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 cm^2

Answer 2
