Question

the volume of a cuboid is 1280m. Its breadth and height are in the ratio of 5:4 and length is 16m.find the breadth​

Answer 1

breadth = 10m

Explanation:

lets take the breadth 5x, so height will be 4x

Volume of cuboid= height * length * breadth

= 4x * 5x * 16 = 1280m^3

=20x^2= 80

=x^2=4

=x=√4

∴ x=2

so height will be = 4x = 4 * 2 =8m

so breadth will be = 5x = 5 * 2 =10m
