The amount of wrapping paper that he needs to cover the pyramid will be 105 square inches.
<h3>What is Geometry?</h3>
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Henry has a box in the shape of a square pyramid.
He wants to wrap the box with paper.
If the base has side lengths of 5 in. and the lateral height is 8 in.
Then the amount of the wrapping paper that he needs to cover the pyramid will be
Thus, the amount of wrapping paper that he needs to cover the pyramid will be 105 square inches.

Answer:
1.179.17
Step-by-step explanation:
area of triangle= height*base/2=25.48
there are 4 triangles so multiply 25.48*4=101.92
Since it’s a regular octagon, all the sides are equal to = 4cm
Like shown above in the diagram, the sides of the octagon can be extended such that it forms a square.
According to Pythagorean theorem, x2 + x2 = 42; 2x2 = 16
x = √8cm
Total side length for the square= 4 + √8 + √8 = 9.657cm
Area of square= (9.657cm) 2 = 93.25cm2
Area of 4 triangles= 4 (1/2 * √8 * √8) = 16.0cm
Area of octagon, A = Area of square – Area of 4 triangles = 93.25 – 16.0 = 77.25cm2
now add 101.92+77.25=179.17
Answer:
Step-by-step explanation:
y - 5 = 1/2(x - 4)
y - 5 = 1/2x - 2
y = 1/2x + 3
Congruent means the same so all you need to do is find the pair of polygons that look identical or the same.
