1. To paint the floor of a sports hall, 23 cans of paint were purchased, each weighing 25 kg, the length of the sports hall is 65 m, and the width is 32 m. Will there be enough paint if 250 g of paint is required per 1 m $^{2}$?
1. 2) $65 \times 32=2080 \mathrm{~m}^{2}$ - area of the hall;
2) $250 \times 2080=520000 \text{ g}=520$ kg - amount of paint required to paint the hall;
3) $25 \times 23=575$ kg - total amount of paint available;
4) $575>520-$ the paint will be enough.

Answer: the paint will be enough.
