Formula for Surface Area of a Prism= S=(Perimeter*Height)+(2*Area of the base) Plug in the values you know and then solve for height:)

3. Kash_TheSmartGuy

Here is the equation for your problem: $48.735=[(2*2.7)+(2*5.6)]x+2*(2.7*5.6)$$48.735=(5.4+11.2)x+30.24$$48.735=16.6x+30.24$$(48.735-30.24)=16.6x+(30.24-30.24)$$\frac{ 18.495 }{ 16.6 }=\frac{ 16.6x }{ 16.6 }$$Height=1.11$ So your answer= 1.11
