What is square pyramid?A square pyramid has a square base and four lateral faces in geometry. A pyramid is a polyhedron with a base and three or more triangular faces that meet above it . A square pyramid, also known as a pentahedron, is a three-dimensional geometry with a total of five faces.
How to solve?As ancient pyramid models were in shape of square pyramid hence we apply
[tex]A = a(a + \sqrt{ (a^{2} + 4h^{2} ))}[/tex]
where a =25cm
and h=30 cm
[tex]A = 25(25 + \sqrt{ (25^{2} + 4(30^{2}) ))}[/tex]
=25(25+65)
=2250[tex]cm^{2}[/tex]

Prove: AC=25
Drag and drop reasons into the boxes to correctly complete the proof.
Statement Reason
Point C is the midpoint of AB¯¯¯¯¯. Given
AC=7x−10; CB=3x+10 Given
AC=CB Definition of midpoint
7x−10=3x+10 Response area
4x−10=10 Response area
4x=20 Addition Property of Equality
x=5 Response area
AC=7(5)−10 Substitution Property of Equality
AC=35−10 Simplify.
AC=25 Simplify.
Answers
Answer:
See proof below
Step-by-step explanation:
If C is the midpoint of AB, then AC = CB
Given
AC=7x−10;
CB=3x+10
Then 7x - 10= 3x+10
Add 10 to both sides
7x-10+10 = 3x +10+10
7x = 3x + 20
7x - 3x = 10+10
4x = 20
x = 20/4
x = 5
Get AC
AC = 7x - 10
AC= 7(5) - 10
AC = 35-10
AC = 25 (Proved)
