if the length, breadth and height of a cuboid are in ratio 5:4:3 and its total surface area is 376 sq.m
Find dimensions of cuboid​

Answer 1

Answer:

length= 5(2)= 10 m

breadth= 4(2) = 8 m

height = 3(2) = 6 m

Step-by-step explanation:

For the given cuboid suppose,

length= 5x

breadth= 4x

height = 3x

Total surface area of cuboid = 2(lb+bh+hl)

376 = 2 [(5x*4x) + (4x*3x) + (3x*5x)]

376= 2 (20x2 + 12x2 + 15x2)

376/2 = (47x2)

188 = 47x2

x2 = 188/47

x2 = 4

x = 2

So, dimensions of cuboid will be

length= 5(2)= 10 m

breadth= 4(2) = 8 m

height = 3(2) = 6 m
