Given,
The length of the rectangular prism is 8 cm.
The breadth of the rectangular prism is 6 cm.
The height of the rectangular prism is 7 cm.
The altitude of triangular prism is 7 cm.
The measure of length and width of the triangular prism is 6 cm and 6 cm.
Required:
Volume of rectangular prism, triangular prism and composite prism.
The volume of rectangular prism is calculated as:
[tex]\begin{gathered} Volume\text{ =length}\times breadth\times height \\ =8\times7\times6 \\ =336\text{ cm}^3 \end{gathered}[/tex]
Hence, the volume of the rectangular prism is 336 cm^3.
The volume of triangular prism is calculated as:
[tex]\begin{gathered} Volume\text{ =}\frac{1}{2}\times l\text{ength}\times breadth\times height \\ =\frac{1}{2}\times6\times7\times6 \\ =126\text{ cm}^3 \end{gathered}[/tex]
Hence, the volume of the triangular prism is 126 cm^3.
