Question

A cuboid has a total surface are of 160 m^2 and lateral surface are of 120 m^2.Find the it's base

Answer 1

Total surface area =lateral surface area+area of Base +area of top
Area of Base =area of top
=>total surface area=lateral surface area+2area of base
2Area of base=160-120=40m^2
Area of base=40/2=20m^2
