The answer is 24. There is 2 width sides and 2 length sides. Let's say the width measurement is x. The 2 sides for width equals 2x. The 2 length sides equals 4x because there twice has long has the width which means that each length side is 2x. 2x plus 4x equals 6x. 6x=24 You divided 24 with 6 which gives you 4. That means that both width sides are 4 units long and the length sides are 8 units long. 4+4+8+8=24, 4 times 8=24

Change your fractions into decimals.
1/2 = 0.5
1/3 = 0.33 (rounded)
5.5 x 2.33 = 12.815
12.815 is your answer
hope this helps
The correct structure of the question is as follows:
The function f(x) = x^3 describes a cube's volume, f(x) in cubic inches, whose length, width, and height each measures x inches. If x is changing, find the (instantaneous) rate of change of the volume with respect to x at the moment when x = 3 inches.
Answer:
Step-by-step explanation:
Given that:
f(x) = x^3
Then;
V = x^3
The rate whereby V is changing with respect to time is can be determined by taking the differentiation of V
dV/dx = 3x^2
Now, at the moment when x = 3;
dV/dx = 3(3)^2
dV/dx = 3(9)
dV/dx = 27 cubic inch per inch
Suppose it is at the moment when x = 9
Then;
dV/dx = 3(9)^2
dV/dx = 3(81)
dV/dx = 243 cubic inch per inch
