Question

surface area of vertical faces of cube is 1600cm^3 find the volume of cube

Answer 1

this question is wrong becuse area never be in cubic cm ???? if it is cm^2 then ans will be

surface area of 4 faces are=4a^2

and given that 4a^2=1600
a^2=1600÷4
a^2=400
therefore a=20
volume of cube =a^3
= 20^3
volume of cube =8000

Answer 2

area of cube
area=4a^2
1600=4a^2
1600/4=a^2
400=a^2
20=a

volume of cube=side^3
=20^3
=8000 cm^2


your answer is that
