This pretest was made to see what schema a student poses on the topic of volume (specifically with rectangular prisms) It is a way for me to see how I should differentiate my instruction in the classroom
If I know that V = l x w x h
than I can say that V = 4 cm x 3 cm x 12 cm
which means V = 144 cm cubed
If l know length x width = a rectangles area
3 cm x 4 cm = 12 cm squared
From looking at the picture I can see that the product of 3 cm and 4 cm are the base of the rectangular prism
If I multiply the new product 12 cm squared by the height of the rectangular prism which is 12 cm then I will
come get 144 cm cubed.
Does this mean that [blank_start]V = l x w x h is equal to V = b x h ?[blank_end] (b= base)
