Answer:
![864\ in^{2}](https://tex.z-dn.net/?f=864%5C%20in%5E%7B2%7D)
Step-by-step explanation:
The figure is a cube
The surface area of a cube is equal to
![S=6b^{2}](https://tex.z-dn.net/?f=S%3D6b%5E%7B2%7D)
where
b is the length side of the cube
In this problem we have
substitute
![S=6(12^{2})=864\ in^{2}](https://tex.z-dn.net/?f=S%3D6%2812%5E%7B2%7D%29%3D864%5C%20in%5E%7B2%7D)
Shaun invested $176,250 into the new business.
Marcus invested half of the $940,000 so the amount that Shaun and Tristan invested is:
= 940,000 / 2
= $470,000
Shaun and Tristan invested in the ratio 3:5.
The amount that Shaun invested is:
<em>= (Ratio of Shaun / Sum of the ratios) x Amount both invested </em>
= (3 / (3 + 5 )) x 470,000
= 3/8 x 470,000
= $176,250
In conclusion, Shaun must have invested $176,250 into the business.
