Question

find the total surface area of cube of side 12cm
​

Answer 1

Answer:

864 cm square

Step-by-step explanation:

A=6a2=6·122=864cm²

Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• In this question, we are asked to find the Total Surface Area of the cube with the side of 12 cm.
• So, to find the Total Surface Area, we must use of :

$\boxed{ \sf Total \: Surface \: area = 6a^2 }$

Here, we have to multiply the side with the side. Then, we have to multiply that value by 6.

Answer :

• 864 cm²

Given :

• Side = 12 cm

To find :

• Total Surface Area of Cube

Solution :

Total Surface Area = 6a²

                                = 6 × (12)²

                                = 6 × 144

                                = 864

Therefore, the Total Surface Area is 864 cm².
