Answer:
2 sheets of paper
Explanation:
Divide 550 ÷ 6 to find out how many cubes can be made.
Either on a calculator or by pencil and paper. You get:
550 ÷ 6 = 91.666...
They can make 91.
91 × 6 = 546
They used up 546 papers.
550 - 546 = 4
They have 4 papers leftover.
They need 2 more papers to make another cube.
