The volume of a cube is 27 cm³. If the cost of painting
the cube is Rs. 25 per cm², then find the cost of painting five faces of the cube.Solution
Let the length of the edge of the cube be ‘x’ cm.
Volume of cube = x³

Area of five faces of the cube = 5x² = 5 × 3 × 3 = 45 cm²
Required cost = 45 × 25 = Rs. 1,125
