Rectangle prism with length 20inches, width 18inches and height 10inches. Suppose water is pumped out of the aquarium at a rate of 360in^3 per min. If the aquarium starts completely full how many mins will it take to empty it

10 minutes

Step-by-step explanation:

To solve this , we need to first calculate the volume of the rectangular prism. Let’s say this is V.

Mathematically, V = w h l where w, h and l are width , height and length respectively.

V = 20 * 18 * 10 = 3600 in^3

Now to get the number of minutes, we divide the volume by the draining rate.

That would be 3600/360 = 10 minutes

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the correct answer is 1: 2
