Answer:

Length 1 1/4 = 10 /8 = 10 cubes L

width = 5/8 = 5 cubes W

Height = 3/4 = 6/8 = 6 cubes H

10 x 5 x 6 = 300 little cubes

Answer: D . 300

Step-by-step explanation:

First find the volume of the rectangular prism with the dimension .

To find the volume, multiply the length by the width by height.

The length is 1 1/4 turn it into an improper fraction.

1 1/4 = 5/4

Now multiply the three fractions

$\frac{5}{4}$ * $\frac{5}{8} * \frac{3}{4}$ = $\frac{75}{128}$

Now notice that the that in the second statement it says the side length of the cube is 1/8. So we need to find the volume of a single cube multiply the length by the with by the height. All sides of a cube are equal so you can just cube the side length to find the volume.

V= s^3

V= (1/8)^2

v = 1/512

Now since we know that the volume of a single cube is 1/512 will will divide the volume of the rectangle by the volume of cubes to find out how many cubes are needed to fill the rectangular prism.

$\frac{75}{128} / \frac{1}{512}$ = 38400/128 = 300
