Answer:
16
Step-by-step explanation:
The dimensions of the base of the prism are 4" by 2"; the height is 2".
Looking at the base, we see that (4)(2), or (8) 1" cubes would cover it exactly and wholly. We'd have a 3-dimensional prism with one layer of 1" cubes.
Now if we add a second layer right on top of the first layer, we'd have used (16) 1" cubes.
No? I'm pretty sure it wouldn't be because 25 to 16 and then 5 to 4 if you multiplied by 5 it would be 25 to 20 so no.
Answer:
10 inches
Step-by-step explanation:
6x-2+6x-2+3x+1=42
12x-4+3x+1=42
15x-3=42
15x=45
x=3
Plug x=3 into 3x+1
3*3+1
9+1=10
Length of base is 10 inches
