Answer: 25
Step-by-step explanation:
Plug in x to the expression.
When there is the same base of exponents is being multiplied the exponents add together and the base stays the same.
So this simplifies to, .
This then solves to 25.
Answer:
Step-by-step explanation:
If we solve for the surface area for each of the 14 cubes, we will come up with a surface area larger than the shape. The best way to go around this is to solve for each face of the shape.
The shape has a total of 42 faces.
The volume of a cube is s³, each cube is or can be converted to
. So a single cube have edges that are
.
The area of a single face of each cube is . We can also write this as
.
Now that we have the area of a single face in the shape, we simply multiply the area by 42 faces.
Surface Area = x 42
Surface Area =
