Two cubes each of volume `27 cm^3` are joined end to end to form a solid. Find the surface area of the resulting cuboid.

Text Solution

Verified by Experts

The correct Answer is:
Side of cube `= root(3)(27) = 3 cm `
Length, breadth and height of cuboid is `3 + 3 = 6cm, 3 cm , 3 cm ` respectively.
Surface Area of cuboid `= 2 ( 6 xx 3 + 3 xx 3 + 3 xx 6 ) = 90cm^(2)`
