For number 7 what is the formula for volume of a cube
Answer: 38
Step-by-step explanation:
3.8=19/5
u have to flip the reciprocal to divide by fraction so 1/10 will be just 10
Then u get 19/5 x 10
You can reduce the GCF so it would be 19 x 2
19 x 2 = 38
Or you can plug it into your calculator (3.8 x .1)
Answer:
2. 
Step-by-step explanation:
We have been given an expression 
and we are asked to find equivalent expression to our given expression.
Using fraction rule 
we can write our expression as: 
.
Upon dividing 10 by 5 we will get,
Upon using exponent property for quotient 
we will get,
Therefore, our expression simplifies as and 2nd option is the correct choice.
Answer:
160 in^2.
Step-by-step explanation:
I guess this is a prism with 6 faces so the surface area is:
2 * 8 * 4 + 2 * 8*4 + 2*4*4
= 64 + 64 + 32
= 160 in^2.
