Someone will be glad to check your answers.
1. To convert millimeters to centimeters, you can divide the measurement by 10 since there are 10 millimeters in 1 centimeter. So, to convert 8,420 millimeters to centimeters, you divide 8,420 by 10.
8,420 millimeters ÷ 10 = 842 centimeters
Therefore, the answer is 842 cm.
2. The formula for the area of a triangle is A = (1/2) * base * height. Given that the base, b, is 17 yd and the height, h, is 11.6 yd, you can plug these values into the formula to find the area.
A = (1/2) * 17 yd * 11.6 yd
A = (1/2) * 17 * 11.6
A = 98.6 yd²
Therefore, the area of the triangle is 98.6 yd².
3. To find the volume of a square sandbox, you can use the formula V = side length * side length * depth. Given that the side length is 3 feet and the depth is 1.05 feet, you can plug these values into the formula to find the volume.
V = 3 ft * 3 ft * 1.05 ft
V = 9 ft³ * 1.05 ft
V = 9.45 ft³
Therefore, Maija should order 9.45 ft³ of sand.
