Question

Find the lateral surface area of a cube whose total suface area is 726 cm².​

Answer 1

Answer:

6a³ = 726

a³ = 726/6

a³ = 121

a = √121

a = 11 cm

Ans

Answer 2

Answer:

Find the lateral surface area of a cube whose total surface area is 726 cm².

Step-by-step explanation:

from the given question:

The total surface area of cube=$6a^{2}$=726$cm^{2}$

from this we get:

                       $6a^{2} =726\\a^{2} =726/6\\a^{2} =121\\\\a=\sqrt 121\\ =11cm$

therefore, lateral surface area=11cm
