Question

total surface area of a cuboid is 2200cm and its lateral surface area is 1000cm what is the area of its base

Answer 1

Tsa of cuboid =220cm square and Lsa of cuboid =1000cm square so if you subtract both ie tsa-lsa=2200-1000=1200 cm square which is equal to area of top and base so 2(lxb)=1200 and you would get lxb=600 cm square
