The dimensions of the rectangular prism are 12 cm x 15 cm x 18 cm. if the dimensions of the rectangular prism are increased by 3, then find the volume of the new prism.

5670 cm^3 or 5670cm cubed

Step-by-step explanation:

Original sides-

12, 15, 18

After increasing by 3-

15, 18, 21

Finding the volume of a rectangular prism is length*width*height.

=15*18*21

=270*21

=5670

Therefore, the volume of the new prism is 5670cm cubed.

Hope this helped^^

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

i believe the answer is letter c) 8
