We know that the side lengths of the square base are: x * x. The volume is 12, so for now, let's say that y is the other side length. Then, x * x * y = 12. We can solve for y: y = 12/x^2. Now, we find the surface area of the 5 sides.
Four of the sides have the same area: x * (12/x^2) = 12/x, so we multiply this by 4: 48/x.
The last side is the base: x * x = x^2.
We add 48/x to x^2:
x^2 + 48/x
So, the answer is the fourth choice, (d).
Answer:
300 dollars
Step-by-step explanation:
250 x 0.2= 50
250 + 50=300
Answer:
the sides are 5ft long
Step-by-step explanation:
since it is a cube we know each side is the same and the cube root of 125 is 5
Answer:
7
Step-by-step explanation:
first put them in order
5,6,6,8,9,9
now the ones that are in the middle are 6 and 8 so we find the average by adding them then dividing by 2
6+8=14/2=7
