The formula for volume of a PRISM is V=(area of the base) x (height of prism).This prism is a composite figure with 2 prisms combined. Find the volume of each prism separately then add the volumes together. (3 points)Part 1: Find the volume of the RECTANGULAR PRISM: YDS3Part 2: Find the volume of the TRIANGULAR PRISM: YDS3Part 3: Find the SUM of the volume of the 2 prisms: YDS
Part 1: Find the volume of the RECTANGULAR PRISM:
Area of the base = (45 cm x 17 cm) = 765 cm²
Height of prism = 18 cm
Volume = 765 cm² x 18 cm = 13770 cm³
Part 2: Find the volume of the TRIANGULAR PRISM:
Area of the base = (17 cm x 20 cm) / 2 = 170 cm²
Height of prism = 45 cm
Volume = 170 cm² x 45 cm = 7650 cm³
Part 3: Find the SUM of the volume of the 2 prisms:
13770 cm³ + 7650 cm³ = 21420 cm³
The total volume of the composite figure is 21420 cubic centimeters.
