the prism is filled completely, that means volume of prism = sum volume of cubes
volume of a cube =h^3, volume of each cube = 14cmx14cmx14cm=2744cm^3
volume of 2304cubes = 2304 x 2744cm^3=6322176cm^3
so the volume of prism = <span>6322176cm^3</span>
Answer:For this case, the first thing we must do is define variables.
x: amount of time Miguel uses to complete the task.
y: amount of time Maria uses to complete the task.
We write the system of equations:
x + y = 60
y = (1/2) x
Solving the system we have:
x = 40 minutes
y = 20 minutes
