Step-by-step explanation:
Given : Rectangular prism has a surface area of 56 square units.
To find : FInd dimensions of prism.
Solution : we have given that Surface area of rectangular prism = 56 units.
Formula of Surface area of rectangular prism = 2(wl+hl+hw)
l = length , w = width , h = height.
Surface area of rectangular prism = 2( 2*2 + 2 *6 + 6 *2 )
Surface area of rectangular prism = 2( 4 + 12 +12)
Surface area of rectangular prism = 2(28)
Surface area of rectangular prism = 56.
Therefore, 2 by 2 by 6.
