Question

How many cups will stack to the top of the door frame?
Explain why...

Answer 1

157 cups

Explanation:

First, convert in to cm

83.375 in * 2.54 Cm/in = 211.77 cm

Each cup adds 1.3 cm to the (9.2 - 1.3 cm) base (Base is 7.9)

211.77 = 7.9 + 1.3 x X is the number of cups

X = 156.9 = ~ 157 cups
