8 meters = 80 decimeters, 6 meters = 60 decimeters, 80 × 60 ^ (2 × 2) = 4800 ^ - 4 = 1200 (pieces); answer: at least 1200 such square bricks are needed
The length of a classroom is 8 meters and the width is 6 meters. How many square bricks do you need at least to pave the floor with 4-decimeter-long square bricks?
8 meters = 80 decimeters, 6 meters = 60 decimeters, 80 × 60 ^ (4 × 4) = 4800 ^ 16 = 300 (pieces) a: at least 300 such square bricks are required
The floor of the classroom is 8 meters long and 6 meters wide, and the floor is paved with square bricks with a side length of 4 decimeters. How many square bricks do you need at least? If each square brick costs 60 yuan, how much will it cost altogether
8 * 6 / (0.4 * 0.4) = 300 pieces
60 * 300 = 18000 yuan
