A sealed rectangular container 4 cm by 8 cm by 16 cm is sitting on its smallest face. In this position the water level is 4 cm from the top. How many centimeters from the bottom will the water level reach if the container is turned and placed on its largest face?

height of water in the container is 3 cm.

Step-by-step explanation:

Given;

A sealed rectangular container, measuring 4 cm by 8 cm by 16 cm

the height of the container is 16 cm, when filled with water at 4 cm level from the top, thus, the height of water in the container is (16 cm - 4cm) = 12cm

Volume of water in the container when it is sitting on its smallest face = 4 cm x 8 cm x 12 cm = 384 cm³

Volume of water in the container when it is sitting on its largest face = 8 cm x 16 cm x h

where;

h is height of water in the container

384 = 8 x 16 x h

384 = 128h

h = 384 / 128

h = 3 cm

Therefore,  height of water in the container is 3 cm.

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

the answer to the expression is 83
