Question

# calculate the surface area of a cube and volume of a cube with the given diagonal length of 15cm

- 3375, 1390
- 4320,3470
- 1350, 3375
- 1570, 3695

Hint:

### Total Surface Area(TSA) of cube = 6a2

Volume of a cube = a3

where, a is side of cube

## The correct answer is: 1350, 3375

### We have given the diagonal of the cube

D= 15 cm

We have to find the Surface area and volume of the cube.

We know that Diagonal of the cube = a

Where a is side of the cube

Comparing with the given value we get

a = 15 cm

Therefore , Surface area of cube = 6a^{2}

= 6(15)^{2}

= 6(225)

= 1350

And, volume of the given cube = a^{3}

= (15)^{3}

= 3375

Therefore the correct option is c)1350, 3375.

Therefore , Surface area of cube = 6a

^{2}

^{2}

And, volume of the given cube = a

^{3}

^{3}

Therefore the correct option is c)1350, 3375.
