Answer:

Step-by-step explanation:
We have the four thickest books from the line plot given by
Two books of
inch thick and the two books of
inch thickness.
So when the two
inch thick book is being piled on the top of a
inch thick books.
Therefore, the total thickness of the pile of books is given by :



Therefore, the thickness of the pile is
.
15
as
15²=12²+9²(using Pythagoras theorem)
or
225= 144+81
225=225
(the Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. )
Solve for X.<span>
-3x + 4 = -8.
</span>X is equal to 4.
Answer:
72cm³
Step-by-step explanation:
Base of the triangular face =3 cm.
Height of the triangular face = 4 cm.
Length of the prism = 12 cm.
Volume of a Prism= Base Area X. length
The base of a triangle prism is a triangle, therefore:
Volume of a Triangular Prism= ½bh X Length
=½ X 3 X 4 X 12
=½ X 144
=72cm³
Volume of the triangular Prism= 72cm³
Answer:
The main difference between a prism and a pyramid is that a prism has two bases, while the pyramid only has one.
The surface area of a prism is equal to the sum of the area of its bases and the lateral area
The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base
