Plug in what we know
P = 20 feet, W = 2 feet
20 = 2L + 2(2)
20 = 2L + 4
16 = 2L, L = 8 feet
Convert feet to inches
1 foot = 12 inches
12 * 8 = 96 inches
Solution: 96 inches
Answer:
8 in
Step-by-step explanation:
since the box is the same length in all sides, it is a cube.
length, width and height are all the same.
the volume is 512 in³.
and the volume of a cube is length×width×height = side length³.
512 = length³
length = 8 = width = height

Answer:
2(10) is implied multiplication
Step-by-step explanation:
( 18+2) + 2(10) ÷4 -2
PEMDAS
Parentheses first
( 20) + 2(10) ÷4 -2
Then exponents ( we have none)
Then multiply and divide from left to right
20 + 20÷4 -2
20 + 5-2
Then add and subtract from left to right
25 -2
