Question

find the side of cude whose surface area is 2400 cm sq​

Answer 1

Answer:

200cm

Step-by-step explanation:

SURFACE AREA OF CUBE =6a^2

6a^2=2400

a^2=400

a=200cm

SO U WILL GET IT AS 200CM

Answer 2

Answer:

Side of Cube = 20 cm

Step-by-step explanation:

Surface area of cube = 6a^2

Also, Given that :- Surface area of cube = 2400 cm^2

=> Surface area of cube = 2400 cm^2

             => 6a^2 = 2400 cm^2

             => a^2 = 2400/6  cm^2

             => a^2 = 400 cm^2

             => a = $\sqrt{400 cm^2$

             => a=  20 cm

Therefore, the side of the cube is 20 cm
