please help me with this. i don't understand it.

Answer:
A. 11160 cubes B. 1395cm^3
Step-by-step explanation:
Volume= length x width x height
Its easiest to solve B. first and use it to solve A.
B. 7.5 x 12 x 15.5 = 1395cm^3 (volume of prism)
A. .5 x .5 x .5 = 1/8cm^3 (which is the volume of the cube)
1395 ÷ 1/8 = 11160
Answer:
Step-by-step explanation:
1) Rectangular prism: l = 7.5 cm ; w = 12 cm ; h = 15.5cm
Volume of rectangular prism = l * w * h
Cubes: edge = 0.5cm
Volume of cube = edge *edge * edge
Number of cubes = Volume of rectangular prism ÷ Volume of a cube
[tex]=\frac{7.5 * 12 * 15.5}{0.5*0.5*0.5}\\\\ = \frac{7.5 * 12 * 15.5*1000}{0.5 *0.5 *0.5 *1000}\\\\= \frac{75 * 12 *155 * 10}{5 * 5 * 5}\\\\= 3 * 12 * 31 * 10\\\\= 11160[/tex]
11160 cubes will fit in the prism.
2) Volume of prism = 7.5 * 12 * 15.5
= 1395 cm³
