Answer 1

The area of the square pyramid is 105 sq inches.

Step-by-step explanation:

Given,

The base of the pyramid (b) = 5 inches

The height (h) = 8 inches

To find the area of the square pyramid.

Formula

The area of the square pyramid = 2bh + $b^{2}$

Now,

The area of the square pyramid = 2×5×8 + $5^{2}$ sq inch

= 105 sq inches

Hence,

The area of the square pyramid is 105 sq inches.

Answer 2

Answer:

Area of the Square pyramid=$108.8 inches^2$

Step-by-step explanation:

Area of a a square pyramid:

                                    $a^2+2a\sqrt{\frac{a^2}{4}+h^2 }$

Base: $side(a)= 5 inches$

$Height=8 inches$

Putting the values in the formula:

Area =    $5^2+2(5)\sqrt{\frac{5^2}{4}+8^2 }$

             $=25+10\sqrt{\frac{25}{4}+64 }\\\\ =25+10\sqrt{6.25+64}\\\\ =25+10\sqrt{70.25}\\\\ =25+10(8.38)\\\\=25+83.8\\\\=108.8inches^2$

Area of the Square pyramid is: $108.8 inches^2$
