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

breadth = 10m

Step-by-step 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

1. 34

2. 268

3. x=14.4

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
