X/4 = 4.3/2.5
x/4 = 1.72
x = 1.72 x 4
x = 6.88
Answer:
840 in^2
Step-by-step explanation:
If the base is square and the side length is 10 inches, the areas of the base and of the top combined is 2(100 in^2).
The height of the prism comes from dividing the volume, 1600 in^3, by the area of the base, 100 in^2: It is 16 in. Then the combined areas of the four sides of the prism is 4(160 in^2).
The total surface area of the prsim is then 640 in^2 + 200 in^2, or 840 in^2.
Since we need to find the final weight, we simply need to add the weight of the truck and the load.
4725 + 7500 = 12225
Your final answer should be 12225 pounds. Hope this helps!
