The LSA of a cube is 324cm. Find its volume and total surface area.
Lateral Surface Area of a cube = 4a2
Given that 4a2 =  324 cm2
a2 = 324 / 4 = 81
a = 9 cm
Volume of a cube = a3
                            = 9 × 9 × 9
                            = 729 cm3
Total surface area = 6a2
                            = 6 × 81
                             = 486 cm2
