Question

5. Find the volume of the composite space figure to the nearest whole number.

Answer 1

The shape is missing but let's consider it a semi-cylinder attached to the rectangular prism.
Given:
radius = 4.5 mm 
Height = 11 mm 

Volume of cylinder = (1/2)(pi)(4.5)^2(11)   (the shape is divided into half)
                           V = 349.89 mm cubed
Volume of prism = L x W x H
                           = 9 x 11 x 6
                           = 594 mm cubed
Total volume of the composite shape = 111.375 + 594 
                                                            = 943.89 mm cubed
Rounded answer = 944 mm cubed.
