Step-by-step explanation:
So hmm notice the picture below
the pyramid itself, is really, just one regular hexagon, at the bottom
and 6 triangles, stacked up at each other at the edges
now, if you just get the area of the regular hexagon, and the 6 triangles, add them up, that'd be the total surface area of the pyramid then
![\bf \textit{area of a regular polygon}\\\\ A=\cfrac{1}{4}\cdot n\cdot s^2\cdot cot\left( \frac{180}{n} \right)\qquad \begin{cases} n=\textit{number of sides}\\ s=\textit{length of a side}\\ \frac{180}{n}=\textit{angle in degrees}\\ ----------\\ n=6\\ s=4 \end{cases}\\\\\\ A=\cfrac{1}{4}\cdot 6\cdot 4^2\cdot cot\left( \frac{180}{6} \right)](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Barea%20of%20a%20regular%20polygon%7D%5C%5C%5C%5C%0AA%3D%5Ccfrac%7B1%7D%7B4%7D%5Ccdot%20%20n%5Ccdot%20%20s%5E2%5Ccdot%20%20cot%5Cleft%28%20%5Cfrac%7B180%7D%7Bn%7D%20%5Cright%29%5Cqquad%20%0A%5Cbegin%7Bcases%7D%0An%3D%5Ctextit%7Bnumber%20of%20sides%7D%5C%5C%0As%3D%5Ctextit%7Blength%20of%20a%20side%7D%5C%5C%0A%5Cfrac%7B180%7D%7Bn%7D%3D%5Ctextit%7Bangle%20in%20degrees%7D%5C%5C%0A----------%5C%5C%0An%3D6%5C%5C%0As%3D4%0A%5Cend%7Bcases%7D%5C%5C%5C%5C%5C%5C%20A%3D%5Ccfrac%7B1%7D%7B4%7D%5Ccdot%20%206%5Ccdot%20%204%5E2%5Ccdot%20%20cot%5Cleft%28%20%5Cfrac%7B180%7D%7B6%7D%20%5Cright%29)
now, for the triangles, well, area of a triangle is 1/2 bh, as you'd know, and you have both
80 1.5 because 10 times 8 equals 80 plus 1.5 equals 80.1.5
For a vertical projectile, the equation of motion is expressed h(t)=g+bt+c, where g is gravity, b is the initial upward velocity, and c is the starting height. The maxima of this equation is given by -b/2g, which in this case would be -56/-32, or 1.75 seconds after launch
