Question

find the total surface area ans lateral surface area of a cube whose edge is 30 cm

Answer is 5400 cm²

answer me fast ​

Answer 1

Answer:

Step-by-step explanation:

Lateral surface area of a cube = 4a²

                                                 = 4*30²

                                                 = 4*900

                                                 = 3600 cm²

Total surface area of cube = 6a²

                                            = 6*30²

                                            = 6*900

                                            = 5400 cm²

Answer 2

Given:

The value of the edge of a cube is 30 cm each.

To find:

The Total Surface Area (TSA) of the cube and

The Lateral Surface Area (LSA) of the cube

Now,

• The formula to find the Total Surface Area (TSA) of the cube is

$\boxed{\red{\rm{6(side)^{2}\ unit\ sq.}}}$

So,

TSA of the cube is

= 6 * (30)²

= 6 * 900

= 5400 cm sq.

Now,

• The formula to find the Lateral Surface Area (LSA) of the cube is

$\boxed{\purple{\sf{4(side)^{2}\ unit\ sq.}}}$

So,

LSA of the cube is

= 4 * (30)²

= 4 * 900

= 3600 cm sq.

Hence,

The Total Surface Area of the cube is 5400 cm sq.

And

The Lateral Surface Area of the cube is 3600 cm sq.

The formula to find the volume of a cube is

= (side)³ unit cube.
