Question

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).

12 in³

Explanation of Solution

Given information: Base length( l ) of pyramid is 6 inches

Base height ( w ) of pyramid is 3 inches

Height( h ) of pyramid is 4 inches

Formula used:The volume of the Pyramid, V Holt Mcdougal Larson Pre-algebra: Student Edition 2012, Chapter 10.8, Problem 8E , additional homework tip 1

Where as B is the base area of the pyramid

Base of the pyramid is right triangle

( Holt Mcdougal Larson Pre-algebra: Student Edition 2012, Chapter 10.8, Problem 8E , additional homework tip 2 )

Calculation:Substituting value of Base length( l ) and Base width( w ) of pyramid to calculate base area,
