1.	) :l5 night.What is the cost of metal sheet required to prepare two cuboidal boxes ofdimensions 1 m x 50 cm x 1.5 m at the rate of ? 120 per m2?
Answer» Surface area of cuboid box = 2(lxb) + 2(bxh) + 2(lxh)= 2(1x.5 + .5x1.2 + 1x1.5)= 2(.5 + .6 + 1.5)= 2(2.6)=5.2 m^2 Surface area for 2 box = 2 x 5. 2 = 10.4Cost of metal sheet = 10.4 x 120= Rs 1248

Answer»

Surface area of cuboid box = 2(lxb) + 2(bxh) + 2(lxh)= 2(1x.5 + .5x1.2 + 1x1.5)= 2(.5 + .6 + 1.5)= 2(2.6)=5.2 m^2

Surface area for 2 box = 2 x 5. 2 = 10.4Cost of metal sheet = 10.4 x 120= Rs 1248
