Answer:

Therefore Surface Area of the Pyramid is 736 cm².

Step-by-step explanation:

Given:

Square Pyramid,

Base = 16 cm = side of Square

Altitude of Triangular part = 15 cm

To Find:

Surface Area of the Pyramid = ?

Solution:

Surface Area of the Pyramid will be given as

[tex]\textrm{Surface Area of the Pyramid}=\textrm{Area of Square base}+4\times \textrm{Area of Triangle}[/tex]

Now for Area of Square,

[tex]\textrm{Area of Square base}=Base\times Base[/tex]

Substituting the values we get

[tex]\textrm{Area of Square base}=16\times 16=256\ cm^{2}[/tex]

Now for Area of Triangle we have,  

[tex]\textrm{Area of the Triangle } = \dfrac{1}{2}\times Base\times Altitude[/tex]

Substituting the values we get

[tex]\textrm{Area of the Triangle} = \dfrac{1}{2}\times 16\times 15=120\ cm^{2}[/tex]

Now Substituting Area of Square and Area of the Triangle in Surface area we get,

[tex]\textrm{Surface Area of the Pyramid}=256+4\times 120=736\ cm^{2}[/tex]

Therefore Surface Area of the Pyramid is 736 cm².
