એક સમઘનની બાજુની લંબાઈ 10 મીટર છે તો તેનું પૃષ્ટફળ શોધો

Answer 1

Given:

એક સમઘનની બાજુની લંબાઈ 10 મીટર છે તો તેનું પૃષ્ટફળ શોધો

Find the surface area of ​​a cube if its side length is 10 meters

To find:

The surface area of ​​a cube

Solution:

The length of each side of the given cube, a = 10 m

Finding the Lateral Surface Area of the cube:

We know,

$\boxed{\bold{L.S.A. \:of\:a\:cube = 4a^2}}$

Therefore,

The lateral surface area of the given cube is,

= $4 \times 10^2$

= $4 \times 100$

= $\boxed{\bold{400\:m^2}}$

Finding the Total Surface Area of the cube:

We know,

$\boxed{\bold{T.S.A. \:of\:a\:cube = 6a^2}}$

Therefore,

The total surface area of the given cube is,

= $6 \times 10^2$

= $6 \times 100$

= $\boxed{\bold{600\:m^2}}$
