Question
A box is in the form of a cube with an edge 8 cm long, find the cost of a painting outside the box and on all the surfaces at the rate of Rs 7 per m2.
- 2688
- 4688
- 2644
- 4624
Hint:
Total Surface Area(TSA) of cube = 6a2
where, a is side of cube
The correct answer is: 2688
For finding the cost of painting outside the box we have to first find the total surface area of the cube given,
TSA of the given cube = 6a2
= 6 (8)2
= 6(64)
= 384
The cost of painting outside the box = (TSA)(7)
= (384)(7)
= 2688
Therefore the cost of painting outside the box is Rs.2688
Therefore, the correct option is a)2688.
The cost of painting outside the box = (TSA)(7)
Therefore the cost of painting outside the box is Rs.2688
Therefore, the correct option is a)2688.
