72 is the volume because u multiply 12 times two then multiply by 6
The volume of the composite solid shown in the diagram is: 80 ft.³.
<h3>What is the Volume of Composite Solid?</h3>
Volume of the composite solid = volume of triangular prism + volume of triangular pyramid.
Volume = 0.5 × base of triangle × height of triangle × length of prism + 1/3 × Base area × Height = 0.5 × 8 × 5 × 3 + 1/3 × 0.5 × 8 × 5 × 3
Volume = 60 + 20
Volume of the composite solid = 80 ft.³.

The answer is x=−4 and y=−3
Given:
five times a number = 5x
decreased by 8 = 5x - 8
is at most 10 = maximum is 10 so less than or equal to 10
more than twice the number = greater than 2x.
2x < 5x - 8 <u><</u> 10
5x - 8 <u><</u> 10
5x - 8 > 2x
****
5x - 8 <u><</u> 10 if x = 3.60 then 2x < 5x-8 <u>< </u>10
+ 8 +8 2(3.6) < 5(3.6) - 8 <u><</u> 10
5x <u><</u> 18 7.2 < 10 <u><</u> 10
÷5 ÷5
x <u><</u> 3.60
5x - 8 > 2x x > 2.67; if x = 3
