a dice in the form of cube is in side 3 cm. Two such cubes are placed as showing in the figure resulting in cuboid . What is the total surface area of cuboid formed |
|
Answer» GivenLength of cuboid box(l)=60cmBreadth of cuboid box(B)=40cmHeight of cuboid box(h)=50cmTotal surface area of CUBOIDAL box =2(lb+bh+hl)=2(60×40+40×50+50×60)=2(2400+2000+3000)=2×7400=14,800cm 2 Total surface area of cuboidal box=Rs. 14,800cm 2 (b) SIDE of cube(a)=50cmTotal surface area of a cube=6.a 2 =6×50 2 =6×2500=1500m 2 Total surface area of a cube=1500cm 2 ∴ Hence cuboidal box requires the lesser amount of material to MAKE. |
