Question

A wooden cube shaped box has a total surface area of 486 CM. what is its volume? what will it cost to laminate the outer surfaces of this box at the rate of Rs. 150 per square cm ​

Answer 1

Explanation:

T.S.A of cube= 6a^2

6a^2=486cm^2

a^2=486/6

a=$\sqrt{486/6}$

=$\sqrt{81}$

a = 9cm

volume of cube= a^3

                           =9^3

                           =729cm^3

T.S.A of cube=486 cm ^2

rate of laminating per cm sqaure = Rs.150

therefore for laminating area of 486cm ^2=486*150

                                                                     =Rs.72,900
