Question

a cuboid has a total surface area is 160 m square m and its lateral surface area is 120 m square m find area of its 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

Answer 2

Answer:

2 area of base is equal to = 160-120=40m^2

area of base is = 40/20 = 20m^2

= 20m^2
