Converting all to improper fractions
31/10s = 31/5
5×31s=31×10
155s = 310
s=310/155= 2

20/9=-4/5m
5×20=-4×9m
100=-36m
m=100/-36 = 72 28/36 = 72 7/9

-14/5=-7/2n
-14×2=5×-7n
-28=-35n
n =-28/-35
n=28/35

A right rectangular prism's edge lengths are 10.5 inches, 5 inches, and 2 inches. How many unit cubes with edge lengths of .5 in

Ede4ka [16]

Answer:

840 cubes

Step-by-step explanation:

First we need to find the volume of each one:

Rectangular prism: Volume = 10.5 * 5 * 2 = 105 in3

Cube: Volume = 0.5 * 0.5 * 0.5 = 0.125 in3

Now, to find how many cubes can fit inside the prism, we just need to divide the volume of the prism by the volume of the cube:

Number of cubes = 105 / 0.125 = 840 cubes
