Question

if the total surface area of cube is 1350 square metres find the length width and height of the cube

Answer 1

surface area of cube is nothing but 6a*2 so it's edge is 15 m

Answer 2

hey mate

here is your answer

the t.s.a=1350

let the side be a

we know

that length=width=height for a cube

also

total surface area =6a²

6a²=1350

a²=1350/6

=225

a=±15

but a≠-15

thus the correct answer is 15.
