Question

14. The square on the diagonal of a cube has an
area of 1875 sq. em. Calculate
(i) the side of the cube.
(ii) the total surface area of the cube.​

Answer 1

Answer:

367.4234 sq cm

Step-by-step explanation:

If the area of the diagonal of cube = 1875 sq cm

Then, 1/2*base*height=1875

But the base and height are equal to the side of cube, as cube has equal sides.

So, let the side of cube be x

Then, 1/2*x*x=1875

Or,x^2/2=1875

Or,x^2= 1875*2=3750

Or,x=√3750=61.23724

Then, total surface are=6*61.23724=367.4234 sq cm
