Answer 2

Calculation of the Volume of Rectangular Parallelepipeds

To calculate the volume of a rectangular parallelepiped, you need to multiply its three dimensions: length (a), width (b), and height (c). The formula for the volume of a rectangular parallelepiped is:

Volume = a * b * c

Let's calculate the volumes for the given dimensions:

a) a = 6 cm, b = 10 cm, c = 5 cm: - Volume = 6 cm * 10 cm * 5 cm = 300 cm³

б) a = 30 dm, b = 20 dm, c = 30 dm: - Volume = 30 dm * 20 dm * 30 dm = 18,000 dm³

в) a = 8 dm, b = 6 m, c = 12 m: - To calculate the volume, we need to convert the dimensions to the same unit. Let's convert dm to m: - a = 8 dm = 0.8 m - b = 6 m - c = 12 m - Volume = 0.8 m * 6 m * 12 m = 57.6 m³

г) a = 2 dm 1 cm, b = 1 dm 7 cm, c = 8 cm: - To calculate the volume, we need to convert the dimensions to the same unit. Let's convert cm to dm: - a = 2 dm + 1 cm = 2.1 dm - b = 1 dm + 7 cm = 1.7 dm - c = 8 cm = 0.8 dm - Volume = 2.1 dm * 1.7 dm * 0.8 dm = 2.856 dm³

д) a = 3 m, b = 2 dm, c = 15 cm: - To calculate the volume, we need to convert the dimensions to the same unit. Let's convert dm and cm to m: - a = 3 m - b = 2 dm = 0.2 m - c = 15 cm = 0.15 m - Volume = 3 m * 0.2 m * 0.15 m = 0.09 m³

Therefore, the volumes of the given rectangular parallelepipeds are: a) 300 cm³ б) 18,000 dm³ в) 57.6 m³ г) 2.856 dm³ д) 0.09 m³
