Atriangular pyramid has a triangular base with a height of 1.5 inches and base length of 4 inches, and height of 9 inches. what is the volume ?

Step-by-step explanation:

Volume of a pyramid is:

V = ⅓ AH

where A is the area of the base and H is the height of the pyramid.

The base is a triangle.  Area of a triangle is:

A = ½ bh

where b is the base length and h is the height.

A = ½ (4)(1.5)

A = 3

V = ⅓ (3)(9)

V = 9

The volume is 9 in³.

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
