Question

find the total surface area and volume of a cube whose length is 12cm

Answer 1

TSA of a cube= 6a2
A=12cm
Then putting the value of a in TSA
6(12)^2
864
Tsa of cubw is 864
2_volume=a3
12^3=1728

Answer 2

Answer:

The total surface area of cube is 864 square cm and volume of cube is 1728 cubic cm.

Step-by-step explanation:

Length of Side of cube = 12 cm

Volume of cube = $a^{3}$

Where a is the side of cube

So, volume of given cube = $(12)^{3}$

                                          = $1728cm^3$

Now formula of total surface area of cube = $6a^{2}$

                                                                      = $6(12)^{2}$

                                                                     = $6(144)$

                                                                     = $864 cm^2$

Hence the total surface area of cube is 864 square cm and volume of cube is 1728 cubic cm.
