Question

. The length of a box is twice its breadth and four times
its height. If the volume of the box is 8 cm, find its
lateral surface area.​

Answer 1

Step-by-step explanation:

Let the height of the cuboid is x centimetre

breadth is 2x centimetre

length is 4x centimetre

lateral surface area is 2h (l+b)

total surface area is 2 (lb+bh+hl)

height is 2 cm breadth is 4 cm and length is 8 cm

lateral surface area is 2 (2)(4+8)=4 (12)=48

total surface area is 2h (l+b)+2lb=48+2 (32)=48+64=112

48/112 divide on table of 16 you will get 3/7
