A right prism has a base in the shape of an octagon. The side length of the octagon is 4 inches. The length of the apothem is 4.83 inches. The height of the prism is 12 inches. What is the volume of the prism? Round your answer to the nearest whole number.

cubic inches

927 cubic inches, just took the test!

927 Cubic Inches!

Area of Octagon, using the formula for finding the area of regular polygons (A = 1/2 x apothem x perimeter) : A = 1/2 x 4.83 x 4 (8) - > A = 77.28

Then using the Area of the base, you then multiply it with the height, and you get your volume: 77.28 x 12 = 927 cubic inches
