Answer:
Surface area: 384in
Step-by-step explanation:
To find the surface area, you calculate the area of one side of the cube.
8 x 8 = 64
Once you get the area of one side of the cube, you multiply your new number by the number of sides in the cube. A cube has 6 sides, so you would multiply the area by 6.
64 x 6 = 384
Therefore, your surface area is 384in
6xy+32
You multiply 8x by each number and get
24/4xy+32 You can simplify the 24/4 to get six. so your answer is
6xy+32
Answer:
7.) 16.7
Step-by-step explanation:
7). First you have to find the length of the line with the triangle that is at a 90 angle with the longest side of the triangle
Using the pythagrorem theorem a² + b² = c²
4² + b² = 5²
b² = 5² - 4²
b² = 25 - 16
b² = 9
√b² =√9
b = 3
next you do the same thing to find the missing segment of the longest side
3² + b² = 13²
b² = 169 - 9
b² = 160
b = √160 or ≈ 12.7
12.7 + 4 = 16.7
so 16.7 is the length of that side
2,450, I am not sure if you were trying to multiply.
