Write a numerical expressionfor the volume of eachof the rectangularprisms above. ( 𝟏𝟓 𝒊𝒏. )(𝟏 𝟏 𝟐 𝒊𝒏. )(𝟑 𝒊𝒏. ) ( 𝟏𝟓 𝒊𝒏. ) (𝟏 𝟏 𝟐 𝒊𝒏. )(𝟔 𝒊𝒏. ) ( 𝟏𝟓 𝒊𝒏. )(𝟏 𝟏 𝟐 𝒊𝒏. )(𝟗 𝒊𝒏. ) b. What do all of these expressions have in common? What do they represent? All of the expressions have ( 𝟏𝟓 𝒊𝒏. ) (𝟏 𝟏 𝟐 𝒊𝒏. ). This is the area of the base. c. Rewrite the numerical expressions to show what they have in common. (𝟐𝟐 𝟏 𝟐 𝒊𝒏 𝟐 )(𝟑 𝒊𝒏. ) (𝟐𝟐 𝟏 𝟐 𝒊𝒏 𝟐 )(𝟔 𝒊𝒏. ) (𝟐𝟐 𝟏 𝟐 𝒊𝒏 𝟐 )(𝟗 𝒊𝒏. ) d. If we know volume for a rectangularprism as length times width times height, what is another formula for volume that we could use based on these examples? (Area of the base)(height), or area of the base timesheight. e. What is the area of the base for all of the rectangularprisms? ( 𝟏𝟓 𝒊𝒏. ) (𝟏 𝟏 𝟐 𝒊𝒏. ) = 𝟐𝟐 𝟏 𝟐 𝒊𝒏 𝟐 f. Determine the volume of eachrectangularprism using either method. ( 𝟏𝟓 𝒊𝒏. ) (𝟏 𝟏 𝟐 𝒊𝒏. )( 𝟑 𝒊𝒏. ) = 𝟔𝟕 𝟏 𝟐 𝒊𝒏 𝟑 or (𝟐𝟐 𝟏 𝟐 𝒊𝒏 𝟐 )( 𝟑 𝒊𝒏. ) = 𝟔𝟕 𝟏 𝟐 𝒊𝒏 𝟑 ( 𝟏𝟓 𝒊𝒏. ) (𝟏 𝟏 𝟐 𝒊𝒏. )( 𝟔 𝒊𝒏. ) = 𝟏𝟑𝟓 𝒊𝒏 𝟑 or (𝟐𝟐 𝟏 𝟐 𝒊𝒏 𝟐 )( 𝟔 𝒊𝒏. ) = 𝟏𝟑𝟓 𝒊𝒏 𝟑 ( 𝟏𝟓 𝒊𝒏. ) (𝟏 𝟏 𝟐 𝒊𝒏. )( 𝟗 𝒊𝒏. ) = 𝟐𝟎𝟐 𝟏 𝟐 𝒊𝒏 𝟑 or (𝟐𝟐 𝟏 𝟐 𝒊𝒏 𝟐 )( 𝟗 𝒊𝒏. ) = 𝟐𝟎𝟐 𝟏 𝟐 𝒊𝒏 𝟑 g. How do the volumes of the first and secondrectangularprisms compare? The
𝐀𝐫𝐞𝐚 = 𝟏𝟑 𝟐 𝐟𝐭 𝟐 𝐀𝐫𝐞𝐚 𝟓 𝟑 𝐟𝐭 𝟓 𝟑 𝐟𝐭 volumes of the first and third? 𝟏𝟑𝟓 𝒊𝒏 𝟑 = 𝟔𝟕 𝟏 𝟐 𝒊𝒏 𝟐 × 𝟐 𝒊𝒏.; 𝟐𝟎𝟐 𝟏 𝟐 𝒊𝒏 𝟑 = 𝟔𝟕 𝟏 𝟐 𝒊𝒏 𝟐 × 𝟑 𝒊𝒏. The volumeof the second prism istwicethat of the first becausethe height is doubled. The volumeof the third prism is three timesas much as the first because the height is triplethe first prism’sheight. Determine the volume of the prism.
