The prism is completely filled with 1750 cubes that have edge length of 15 ft.

neonofarm [45]

The volume of the prism = 14 ft³

Solution:

Number of cubes in the prism = 1750

Edge length of each cube (a) = $\frac{1}{5}$ ft

To find the volume of each cube:

Volume of each cube = a³

$$=\left(\frac{1}{5} \right)^3$

Volume of each cube $$=\frac{1}{125} \ \text{ft}^3$

To find the volume of the prism:

Volume of the prism = Volume of each cube × Number of cubes

$$=\frac{1}{125} \ \text{ft}^3\times 1750$

= 14 ft³

The volume of the prism = 14 ft³

X/5=2/3=5/y 2/3 4/9 1

Mademuasel [1]

$\frac{x}{5}= \frac{2}{3} = \frac{5}{y}$
Break the equation into parts;
$\frac{x}{5} = \frac{2}{3} ; \frac{2}{3}= \frac{5}{y}$
Solving for x;
$\frac{x}{5} = \frac{2}{3}$
x= $\frac{10}{3}$
Solving for y;
$\frac{2}{3} = \frac{5}{y} 
y= \frac{3*5}{2} 
y= \frac{15}{2}$
$\frac{x}{y} = \frac{10/3}{15/2}$
$\frac{x}{y} = \frac{4}{15}$
