Stove area = 12 square feet
Refrigerator area = 20 square feet
Entire kitchen floor = 270 square feet
12 + 20 = 32 square feet
270 square feet - 32 square feet = 238 square feet
238 square feet will be needed
Answer:
A. 17 1/2 . . . cubic feet
Step-by-step explanation:
The volume is the product of the length, width, and height. If your calculator doesn't deal with mixed numbers, it can be convenient to use one that does.
(4 ft)(2 1/2 ft)(1 3/4 ft) = 17 1/2 ft³
The volume of the box is 17 1/2 cubic feet.
____
You can also convert the numbers to decimal to use on your calculator:
4 × 2.5 × 1.75 = 17.500
Or convert them to improper fractions:
4 × 5/2 × 7/4 = 35/2 = 17 1/2
r = 1 + cos θ
r = 1 − sin θ
r ≥ 0, 0 ≤ θ < 2π
(r, θ) = (smallest r-value)
(r, θ) =
(r, θ) = (largest r-value)
