Question 5 of 5What is the volume of this composite solid?4 m9 m4 mO A. 198 cubic metersO B. 252 cubic metersO C. 58 cubic metersO D. 150 cubic metersSUBMIT

Answer 1

we must calculate two volume and add

The volume of the figure results from finding the area of ​​the triangle and multiplying it by the width of the figure

so

`\begin{gathered} V_1=(b* h)/(2)* w \\ \\ V_1=(4*3)/(2)*9 \\ \\ V_1=(12)/(2)*9 \\ \\ V_1_{}=6*9 \\ V_1=54 \end{gathered}`

the first area is 54cubic meters

The volume of the figure results from finding the area of ​​the square and multiplying it by the width of the figure

so

`\begin{gathered} V_2=l* l* w \\ V_1=4*4*9 \\ V_1=144 \end{gathered}`

The second area is 144 cubic meters

The total volume is

`144+54=198`

the total volume is 198 cubic meters
