Question

length =?breadth=?height=? surface area = 600m square ( giventhat solid is cube)

Answer 1

surface area = 600 square. m.
$6 {a}^{2} = 600$
${a}^{2} = 100$
$a = 10$
l=10
b=10
h=10

Answer 2

Surface area of a cube=6*side^2

600m^2=6*side^2

Side^2=600m^2/6

Side^2=100m^2

Side =10 m.

Height of cube=length of cube =breadth of cube=10m.
