Question

for a school project, max made a pyramid using 587 sugar cubes. on his way to school 34 of the sugar cubes fell off. when he got to school his friends took 18 more cubes off the pyramid to eat.
estimate how many sugar cubes remain on maxs pyramid.
choose 1 answer:
a 550 cubes
b 1,200 cubes
c 1,820 cubes
d 20 cubes

Explanation:

Step1: Round the numbers

Round 587 to 590, 34 to 30, and 18 to 20.

Step2: Calculate the total number of cubes removed

Add the rounded number of cubes that fell off and were taken: \(30 + 20 = 50\)

Step3: Subtract the total removed from the original

Subtract the total removed from the rounded original number of cubes: \(590 - 50 = 540\)
The closest option to 540 is 550.

Answer:

A. 550 cubes
