Volume of rectangular pyramid:

[tex]v = \frac{lwh}{3} [/tex]

[tex]v = \frac{12 \times 10 \times 3}{3} [/tex]

[tex]v = 120 \: {ft}^{3} [/tex]

Volume of the rectangular prism:

[tex]v = lwh[/tex]

[tex]v = 12 \times 10 \times 7[/tex]

[tex]v = 840 \: {ft}^{3} [/tex]

Total volume:

[tex]v = 120 + 840[/tex]

[tex]v = 960 \: {ft}^{3} [/tex]

pyramid:

lwh/2

=12×10×3/3

=120 ft^3

prism:

whl

=12×10×7

=840 ft^3

all together:

=960 ft^3
