Answer 2

Given : an open box is in shape of a cube

diagonal in the face of a cube is 7 metre long  

To Find : lateral surface area of the box is​

Solution:

Let say Edge length of Cube = a  m

Then Diagonal length = a√2  m

a√2 =  7m

=> a = 7/√2  m

lateral surface area of the box = 4a²

= 4(7/√2)²

= 98 m²

Total Surface area =  5a²  as box is open from top

= 5(7/√2)²

= 122.5 m²
