Find the volume of a pyramid with a square base, where the side length of the base is
8.3 in and the height of the pyramid is 7.3 in. Round your answer to the nearest
tenth of a cubic inch.

The volume of the pyramid is  167.6 cube inch (approx).

Step-by-step explanation:

Given,

Each length (l) of the base of the pyramid = 8.3 in

Height(h) of the pyramid = 7.3 in

To find the volume of the pyramid.

Formula

Volume of the pyramid = ×area of the base×height

Area of the base = l²

Now,

The volume of the pyramid =  ×l²×h

=  ×8.3²×7.3 cube inch = 167.6 cube inch (approx)

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
