Firewood is usually sold by a measure known as a cord. A full cord may be a stack 8x4x4 feet or a stack 8x8x2 feet. What is the volume of a full cord of firewood? A short cord of wood is 8x4 x the length of the logs. What is the volume of a short cord of 2 1/2 foot logs? If you have an area that is 12 feet long and 2 feet wide in which to store your firewood, how high will the stack be if it is a full cord of wood?

step-by-step explanation:

step-by-step explanation:

for volume, add base x height x width

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
