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

Hint: volume of each cube = 1/2 * 1/2 * 1/2

oh you were given that anyway!

so that would be 1/6

I'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.

  • welshfella
yep

  • anonymous
Oh yeah, so 1/8 right? Ye

Thank you you two, I'm supposed to be in 10th grade math buuut I have to retake 6th... Kinda embarrassing.

It's okay! gl<3

well multiply 90 by 1/8 and find the quotient and remainder

While I have you two let me check my work with you if it's fine
anonymous
  • anonymous
A-okay!
anonymous
  • anonymous
So it would be (90*1)/8 right?
anonymous
  • anonymous
Which would come out to be 11.25?
welshfella
  • welshfella
No there are 11 unit cubes but how many of the smaller ones?
welshfella
  • welshfella
90 / 8 = 11 and how many over?
anonymous
  • anonymous
25
anonymous
  • anonymous
Wait no, 2?
welshfella
  • welshfella
11*8 = 88 - that equals 11 unit cubes and there are 90-88 = 2 small ones left
anonymous
  • anonymous
Yes
anonymous
  • anonymous
so it would be c!
welshfella
  • welshfella
right C
