Answer:
32
Step-by-step explanation:
Volumeprism=volumecube times number of cubes
vprism/vcube=number of cubes
vprism=12*5*4.25=255
vcube=side^3=(1/4)^3=1/64
vprism/vcube=255/(1/64)=255*64=16320 cubes
Hello there!☺

Hope this helps!☺
If the two triangles are congruent it means that their side lengths are equal, so we can assume that x = 3x - 8 and so 2x = 8 and x = 4. Hope that helps :)
Answer:
Step-by-step explanation: We have to add how much time it took him to do all of his homework. To do this, we have to add 2/3 and 3/5.
First, we have to find a LCM between 3 and 5.
The LCM between those numbers are 15.
Next we find out what number to multiply 3 by to get 15, we multiply it by 5.
2 * 5 = 10
3 * 5 = 15
Next we find out what number to multiply 5 by to get 15, we multiply it by 3.
3 * 3 = 9
5 * 3 = 15
10/15+9/15=19/15
We are left off with 1 4/15
So it took him 1 hour and 4/15 minutes to do his homework.
