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.
the bottom 45cm
the right side going side to side 17cm
the top 18cm
the ride side going up and down 20cm
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.
