Question

are cuboid has a total surface area of 280 CM and lateral surface area to 210 cm . Find the area of its base
​

Answer 1

Answer:

lateral surface area = 2h(l+b)

LSA =180 cm^2

TSA =2(lb + bh + hl )

TSA =2lb +2(bh+hl)

TSA = 2lb+180

372 = 2lb+180

372-180= 2 lb

192 = 2lb

192/2 = lb

96 = area of base
