The total surface area of this cuboid is 112cm squared find the value of x

 or  

Step-by-step explanation:

we know that

The surface area of a cube is equal to

where

x is the length side of a cube

In this problem we have

substitute in the formula and solve for x

square root both sides

The total surface area of this cuboid is 112 then the value of x is 2.65cm and this can be evaluated by using the total surface area of the cuboid formula.

Given :

The total surface area of this cuboid is 112

The total surface area of the cuboid is given by:

  ---- (1)

where 'x' is the side length of the cuboid.

Now, put the value of the surface area of the cuboid in equation (1).

x = 2.65cm

Therefore, the total surface area of this cuboid is 112 then the value of x is 2.65 cm.
