Describe how the two figures at the right are alike and how they are different. Which box has larger lateral surface area? |
|
Answer» Both the figure have same height & one figure is cube & the other one is cylinder. Given: Diameter of cylinder = 7 cm Radiusof cylinder(r)=7/2 cm Height of cylinder(h)=7 cm Side of CUBE(a)= 7cm Lateral surface area of cylinder =2πrh =2(22/7)(7/2)(7) = 22× 7 = 154 cm² Lateral surface area of cylinder=154 cm² Lateral surface area of cube=4 a² = 4×(7)² = 4× 49 = 196cm² Lateral surface area of cube=196cm² Hence, the cube has larger lateral surface area |
