Question

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

Answer 1

heyya mate....



here is ur answer...⬇️⬇️


side =12 cm

total surface area = area of 1 surface × no. of faces

= 12 cm× 12 cm ×6

= 864cm ^2





volume = side ^3

= 12 cm×12 cm ×12 cm

= 1728 cm^3





hope it helps u .....❤❤❤❤

Answer 2

Answer:

$864\ cm^{2}$

$1728\ cm^{3}$

Step-by-step explanation:

According to the question

The length of a cube,l = 12 cm

we have to find the total surface area and volume of a cube.

we know that,

surface area of cube = $6l^{2}$

                                   = $6\times(12)^{2}$

                                   = 6 x 144

                                   = $864\ cm^{2}$

Now, the volume of a cube = $l^{3}$

                                             = $12^{3}$

                                             = $1728\ cm^{3}$

Hence the total surface area is $864\ cm^{2}$ and volume of a cube is $1728\ cm^{3}$.
