( b ) The shape is the cross-section of a metal prism of length
2.8 meters.
Calculate the volume of the prism in cubic centimetres.
To calculate the volume of the prism, we need to find the area of the cross-section and then multiply it by the length of the prism.
Given that the prism has a cross-section shape, we first need to determine the area of the cross-section. Let's assume the cross-section is a rectangle with dimensions x and y.
If the length of the prism is 2.8 meters, then the area of the cross-section is xy.
Since we don't have the specific dimensions of the cross-section, we can't calculate the exact volume. However, we can provide a general formula for the volume in cubic centimeters:
Volume = (2.8 meters * 100 cm/meter) * (xy) cubic centimeters = 280(x)(y) cubic centimeters.
So, to calculate the exact volume in cubic centimeters, we would need to know the specific dimensions of the cross-section (x and y).
