A sheet of plywood is 5/8 inches thick. How tall is the stack of 21 sheets?

1 answer

To find the total height of the stack of 21 sheets, we need to multiply the thickness of one sheet by the number of sheets.

Thickness of one sheet = 5/8 inches

Number of sheets = 21

Height of the stack = (5/8) * 21 = 105/8 = 13.125 inches

Therefore, the stack of 21 sheets is 13.125 inches tall.
