To find the volume of a prism, you multiply the area of the base by the height. In this case, the base is a rectangle with dimensions 10cm and 4cm, so the area is 10cm x 4cm = 40cm². The height of the prism is 2cm. Therefore, the volume of the prism is 40cm² x 2cm = 80cm³.
55cm x 40cm x 20cm = 21.65 inches x 15.75 inches x 7.87 inches.
55cm x 40cm x 20cm = 21.65inches x 15.75inches x 7.87inches1 inch = 2.54cm55cm = 55cm * 1 inch/2.54cm =21.65 inches40cm = 40cm*1 inch/2.54cm=15.75inches20cm = 20cm*1 inch/2.54cm=7.87inches
The first step in answering this is to work out what the dimensions of the book are. The width is 10cm. The length is 2x the width, which is 2x10 = 20cm. The height is half the width which is 10/2 = 5cm. Thus the dimensions of the book are 10cm x 20cm x 5cm. To work out the volume you multiply these dimensions together: 10x20x5 = 1,000 Thus the volume of the book is 1,000cm3
