Answer:
Total volume of the figure = 1067 cm³
Explanation:
Volume of the composite figure = Volume of the rectangular prism + Volume of the square pyramid
Volume of the rectangular prism = Length × Width × Height
= 10 × 10 × 7
= 700 cm³
Volume of the square pyramid =
![(1)/(3)(\text{Area of the base})* (\text{height})](https://img.qammunity.org/2021/formulas/mathematics/high-school/uedw9c5z5rk88cu74orfyhfsrj22gtcu9c.png)
=
× height
=
![(1)/(3)(10)^2(18-7)](https://img.qammunity.org/2021/formulas/mathematics/high-school/aelxqj0jpj0wm0rs0nymql0ddoz1miszt0.png)
= 366.67 cm³
Total volume of the composite figure = 700 + 366.67 = 1066.67 cm³
≈ 1067 cm³
