Answers
Answer:
Cube 1: 3375 cubed inches, 1350 inches squared.
Cube 2: 512 cubed inches, 384 inches squared.
Step-by-step explanation:
Formula for Volume of a Cube: (s - side length)
Formula for Surface Area of a Cube: (s- side length)
For Cube 1:
The side length's 15 inches.
Find the volume:
The volume of cube one is 3375in³.
Find the surface area:
The surface area of cube 1 is 1350in².
For Cube 2:
The side length's 8 inches.
Find the volume:
The volume of cube two is 512in³.
Find the surface area:
The surface area of cube 2 is 384in².

Final answer:
The surface area of a cube with side lengths of 15 inches is 1350 square inches and its volume is 3375 cubic inches.
Explanation:
To find the surface area of a cube, you need to find the area of each face and then add them up. In this case, since all sides of the cube have the same length, you can use the formula: surface area = 6 * . For a cube with side lengths of 15 inches, the surface area would be 6 *
= 6 * 225 square inches = 1350 square inches.
To find the volume of a cube, you need to multiply the length, width, and height. In this case, since all sides of the cube have the same length, you can use the formula: volume = . For a cube with side lengths of 15 inches, the volume would be
= 3375 cubic inches.
Now, for a cube of side length 8 inches: for the surface area using the first formula, we get 6*(8 inches)² = 384 square inches. Using the volume formula, we get (8 inches)³ = 512 cubic inches.

Answers
If you look at it the pattern is:
Multiply by 4, then divide by 2
4 times 4= 16
16 divided by 2= 8
8 times 4= 32
32 divided by 2= 16
Now you would multiply by 4
16 times 4= 64
multiply by 4, divide by 2, multiply by 4...etc
so what comes next is 16*4=64

answer is A
In this example multiplying 0.035 by 100, we get 3.5 (the value in percent).
Step 1: Move the decimal point two places to the right: 0.035 → 0.35 → 3.5.
Step 2: Add a % sign: 3.5%So, 0.035 is equivalent to 3.5% in percent form.
