1) The volume for a rectangular prism is Length x Width x Height
This is the formula:
V = L x W x H
Length: 4 cm
Width: 4 cm
Height: 9 cm
V = 4 x 4 x 9
V = 16 x 9
V = 144 cm3
2) The Volume for a triangle is: V = L x W x H / 2 (length times width times height divided by 2)
Length: 8 cm
Height: 6 cm
Width: 4 cm
V = (8 x 6 x 4) / 2 (8 times 6 times 4 divided by 2)
V = 192 divided by 2
V = 96 cm3
