3cubes each of volume 27cm^3 are joined end to end. find the surface area of resulting cuboid

126 cm^2

Step-by-step explanation:

side of cube is cube root of volume, so that s × s × s = v, s = (v)^(1/3)

v = 27 cm^3, s = 3 cm.

Cuboid (a/k/a rectangular prism) has sides 3s, s, s, two faces area s × s, four faces area 3s × s, total area 2×s^2 + 4×3×s^2 = 14×s^2 = 14×9 cm^2 = 126 cm^2
