Question

The volume of a closed cubical tank is 1331 cubic metres. Find the cost of painting its complete surface area from outside at the rate of RS 10 per square metres.

Answer 1

Step-by-step explanation:

Volume of a cubical tank= a^3

1331=a^3

3√1331=a

11=a

Surface area of a cubical tank= 6a^2

=6(11)^2

=6×121

=726cm^2.
