Nadya filled a right rectangular prism with cubes that are 1/2 inch long each edge. She stacked 80 cubes in the prism and filled it to capacity. What is the volume of the prism?

Answer

Step-by-step explanation:

The volume of cube

each edge of cube inch

so,

the volume of cube

one cube of  volume cubic inch.

cube of volume cubic inch

so the volume of rectangular prisme equal to volume of 80 cube.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
