Question

find total surface area of cube it side is 7.2cm​

Answer 1

Answer:

311.04 sq. cm

Step-by-step explanation:

Edge= 7.2 cm

6 sides

7.2*6= 43.2

=43.2^2= 311.04 sq. cm

Edge Calculation

a=square root A/6 = square root  311.04/6 = 7.2

Answer 2

Answer:

The total surface area of the cube is $311.04cm^2.$

Step-by-step explanation:

In context to the question asked,

We have to find the total surface area of the cube,

As per the data given in the question,

We have,

Given side of cube = $7.2cm$

The total surface area of a cube is the area covered by all six faces of a cube.

The formula to be used for calculating the total surface area of a cube,

Total surface area = $6a^2$,

By substituting the given value in the above formula,

=> $6 ( 7.2)^2$

=> $6 \times 7.2 \times 7.2$

=> $311.04cm^2$

Hence, the required solution is $311.04cm^2$.
