Question

Find the side of cube whose surface area is 1200 cm2​

Answer 1

Answer:

let side of cube is a

so area of surface of cube =a^2=1200 cm square

a=√(1200)=34.6410162 cm

Answer 2

Answer:

20cm

Step-by-step explanation:

using formula

surface area of cube = 6a^2

we have surface area of cube=1200cm^2

put it in the formula we get

1200cm^2 = 6a^2

200cm^2 = a^2

√200cm^2 = a

a = 20cm

so side of a cube is 20cm.
