Question

Pyramid, in architecture, a monumental structure constructed of or faced with stone or brick and having a rectangular base and four sloping triangular sides meeting at an apex. Pyramids have been built at various times in Egypt, Sudan, Ethiopia, western Asia, Greece, Cyprus, Italy, India, Thailand, Mexico, South America, and on some islands of the Pacific Ocean. Those of Egypt and of Central and South America are the best known.

The volume and surface area of a pyramid with a square base of area a² and height

is given by

v = ² and S = a² + 2a ()*² +h² A pyramid has a square base and a volume of 3y + 18y +27y cubic units.​

Answer 1

Answer:

we have

$S= a ^{2} + 2a\sqrt{(\frac{a}{2}) ^{2} } + h^{2}$

24 and y = 5

thus

$S= 24 ^{2} + 2 * 24\sqrt{(\frac{24}{2}) ^{2} } + 5^{2} = 2 * 24 (12+ \sqrt{12^{2} + 5^{2} }$

= 48 (12 +13) = 1200 sq units

Answer 2

Answer:

1200 sq units

Step-by-step explanation:

We have,

$S-a^{2} + 2a\sqrt[]{(\frac{a}{2} )^{2} } + h^{2}$

Here, $a=24$ & $h=5$

Thus,

$S=24^{2} + 2*24\sqrt[]{12}^{2} +5^{2} = 2*24(12+\sqrt{} ({12^{2} } +5^{2} )\\= 48(12+13)$

=$1,200$ sq units.
