Answer:
2.7 million euros per month
Step-by-step explanation:
Since the room is a rectangular prism, we find the area of the room without its top and bottom, which is the area of the walls, A. So,
A = 2(lh + wh) = 2h(l + w) where l = length of room = 50 m, w = width of room = 40 m and h = height of room = 75 m
Substituting the values of the variables into A, we have
A = 2h(l + w)
= 2(75 m)(50 m + 40 m)
= 150 m × 90 m
= 13500 m²
= 13500 × 1m²
= 13500 × 10000 cm²
= 135000000 cm²
= 1.35 × 10⁸ cm²
Now, since 50 cm² of space = 1 Euro per month, then 1.35 × 10⁸ cm²
= 1.35 × 10⁸ cm² × 1 Euro per month/50 cm²
= 0.027 × 10⁸ Euro per month
= 2.7 × 10⁶ Euro per month
= 2.7 million euros per month
So, the institute will earn 2.7 million euros per month
