Answer :
Final answer:
To find how many cm³ are in 1.25 ft³, you multiply 1.25 by the number of cm³ in one cubic foot, which is 28,316.8466 cm³. The result is approximately 35,396.06 cm³, which means the correct answer is (d) 3.54 x 10⁴ cm³.
Explanation:
To calculate how many cm³ are there in 1.25 ft³, we need to know the conversion factors between cubic feet and cubic centimeters.
One foot is equivalent to 30.48 centimeters, and since we are dealing with cubic measures, we need to cube this conversion factor. Therefore, 1 ft³ is equal to (30.48 cm) x (30.48 cm) x (30.48 cm), which equals 28,316.8466 cm³.
Now we simply multiply this value by the given amount in cubic feet to find the answer: 1.25 ft³ x 28,316.8466 cm³/ft³ = 35,396.05825 cm³, which we can round to 35,396.06 cm³ to match the given significant digits.
The answer that is closest to our calculation is (d) 3.54 x 10⁴ cm³.
