Question

If the volume of cube is 29791 m3m^3​, then find the total surface area of cube in m2.m^2.​​

A.

5733

B.

5766

C.

5794

D.

5784

Correct option is B

Given:
Volume of the cube =  29791 m3.29791 \, \text{m}^3 .
Find the total surface area of the cube in m2 \text{m}^2 ​​
Formula Used:
Volume of a cube:
Volume=a3\text{Volume} = a^3​​
where  a  is the side length of the cube.
Total surface area of a cube:
Surface Area=6a2\text{Surface Area} = 6a^2
Solution:
a3=29791a^3 = 29791
a=297913a = \sqrt[3]{29791}​​
a=31 ma = 31 \, \text{m}
Now, calculate the total surface area using the formula:
Surface Area=6a2\text{Surface Area} = 6a^2
Surface Area=6×(31)2\text{Surface Area} = 6 \times (31)^2
Surface Area=6×961\text{Surface Area} = 6 \times 961
Surface Area=5766 m2\text{Surface Area} = 5766 \, \text{m}^2
Thus, option (b) is right.
