Question

find the lateral surface area and total surface area of a cuboid whose dimensions are:
5.5m,25cm,75000mm ​

Answer 1

Answer:

lateral surface area = 2(l+b) *h

length of the cuboid is 5.5 m

we will change into milimeter so we will multiply by 1000

so the length of the cuboid is 5.5*1000= 5500mm

breadth of the cuboid is 25 cm

we will change into milimeter so we will multiply by 100

so the breadth of the cuboid is 25*100= 2500mm

height = 75000

lateral surface is equal to the 2(5500+2500) *75000= 2(8000) ×75000

16000+75000

91000mm square

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

2(5500×2500+5500×75000+2500×75000)

2(13750000+412500000+187500000)

2(613750000)

1227500000mm square
