Answer:
376 square centimeters
Step-by-step explanation:
When doubled, the new length is 5*2=10 cm, new width is 4*2=8 cm, and new height is 3*2=6 cm.
The surface area of a rectangular prism is given by : ![2(lw+wh+lh)](https://tex.z-dn.net/?f=2%28lw%2Bwh%2Blh%29)
Where l is length, w is width, and h is height
Plugging in the new values we get:
![2(lw+wh+lh)\\=2((10)(8)+(8)(6)+(10)(6))\\=2(80+48+60)\\=2(188)\\=376](https://tex.z-dn.net/?f=2%28lw%2Bwh%2Blh%29%5C%5C%3D2%28%2810%29%288%29%2B%288%29%286%29%2B%2810%29%286%29%29%5C%5C%3D2%2880%2B48%2B60%29%5C%5C%3D2%28188%29%5C%5C%3D376)
The surface area of the enlarged prism = 376 cm^2
