Answer:
80
Step-by-step explanation:
the formula is base times height the height is 10 and the base is 8 so 10 times 8 equals 80
By not turning things in... being late for class... I don't get it
Answer:
70
Step-by-step explanation:
21 times 3 = 63
4410 /63= 70
Answer:
108.82in²
Step-by-step explanation:
The formula for the surface area of the square pyramid is,
![A = a^{2} + 2a \sqrt{\frac{a^{2} }{4} + h^{2} }](https://tex.z-dn.net/?f=A%20%3D%20a%5E%7B2%7D%20%2B%202a%20%5Csqrt%7B%5Cfrac%7Ba%5E%7B2%7D%20%7D%7B4%7D%20%2B%20h%5E%7B2%7D%20%7D)
⇒ <u>h</u> represents the height which is 8in
⇒ <u>a</u> represents the base edge which is 5in
<em>Plug in:</em>
![A = 5^{2} + 2(5) \sqrt{\frac{5^{2} }{4} + 8^{2} } \\\\A = 25 + 10 \sqrt{\frac{25 }{4} + 64 } \\\\A = 35 \sqrt{6.25 + 64} \\\\A = 35 \sqrt{70.25}](https://tex.z-dn.net/?f=A%20%3D%205%5E%7B2%7D%20%2B%202%285%29%20%5Csqrt%7B%5Cfrac%7B5%5E%7B2%7D%20%7D%7B4%7D%20%2B%208%5E%7B2%7D%20%7D%20%5C%5C%5C%5CA%20%3D%2025%20%2B%2010%20%5Csqrt%7B%5Cfrac%7B25%20%7D%7B4%7D%20%2B%2064%20%7D%20%5C%5C%5C%5CA%20%3D%2035%20%5Csqrt%7B6.25%20%2B%2064%7D%20%5C%5C%5C%5CA%20%3D%2035%20%5Csqrt%7B70.25%7D)
A = 108.815
