You use a scale of 1 inch = 280 feet to build a model of the Great Pyramid of Giza. The width of the base of the pyramid is 756 feet. What is the width of your model?
A. 27 in.
B. 3.4 in.
C. 3 in.
D. 2.7 in.
To find the width of the model, we need to divide the actual width of the pyramid by the scale factor:
756 feet ÷ 280 = 2.7 feet
Now we can convert the width to inches by multiplying by 12:
2.7 feet × 12 inches/foot = 32.4 inches
Therefore, the width of the model is approximately 32.4 inches, which rounds to 32.4 inches ÷ 12 inches/inch = 2.7 inches.
So the answer is D. 2.7 in.
