A rectangular prism is completely packed with 90 cubes of edge length fraction 1 over 2 inch, without any gap or overlap. Which of the following describes the volume of this rectangular prism?
11 unit cubes and 1 smaller cube of volume fraction 1 over 8 cubic inch
22 unit cubes and 4 smaller cubes of volume fraction 1 over 8 cubic inch each
11 unit cubes and 2 smaller cubes of volume fraction 1 over 8 cubic inch each
22 unit cubes and 2 smaller cubes of volume fraction 1 over 8 cubic inch each
Could someone teach me the steps please? I reviewed the lesson, I still don't understand

Best ResponseYou've already chosen the best response.0I'm pretty sure the volume of each cube is 1/8. Just divide 90 by 1/8 after that and you'll find the answer.

Best ResponseYou've already chosen the best response.190 / 8 = 11 and how many over?

Best ResponseYou've already chosen the best response.111*8 = 88  that equals 11 unit cubes and there are 9088 = 2 small ones left
