# The Roll of a Lifetime

You probably don’t think about toilet paper too often – until it runs out. Well, if you get the new ‘Forever Roll’ of toilet paper, you’ll think about it even less! This giant roll weighs 2 pounds and is 9 inches in diameter (distance across that circle). It’s so enormous that it needs its own special holder. There are 1,700 squares of TP, which add up to 555 feet of paper. If you unrolled the whole thing, that length would stretch farther than 12 school buses, and would match the height of the Washington Monument! Despite all that, it won’t really last forever like the name says – but at least when you need a refill, you can roll it right home from the store.

Wee ones: How many rolls of toilet paper do you see in the picture?

Little kids: How many 2-pound rolls of toilet paper add up to 10 pounds of paper? Count up by 2s if it helps! Bonus: If normal toilet paper rolls are 5 inches across, which is wider, 2 of those next to each other, or the 9-inch Forever Roll?

Big kids: If a normal roll of toilet paper weighs 1/4 pound, how many normal rolls together weigh the same as the 2-pound Forever Roll? Bonus: If you use the bathroom 4 times a day using 3 squares each time, and you start a new roll first thing on Sunday morning, on what day of the week will you use the 100th square?

The sky’s the limit: Normal toilet paper squares are about 4 inches long. If those 1,700 squares were exactly 4-inch squares, would the roll be longer or shorter than the 555-foot Washington Monument? See if you can figure out a shortcut to solve this!
