Answer:
Second Option
671 m²; 725 m²
Step-by-step explanation:
The lateral area of a triangular prism is:
Where P is the perimeter of the triangular base and h is the height of the prism.
In this case, the perimeter of the triangular base is:
Then the height is 26 m
Then the lateral area of the prism is:
Therefore the surface area of the triangular prism is:
Where 
is the area of the base.
Where b is the base of the triangle and h is the height
In this case:
Finally
The answer is 671 m² and 725 m²
Answer:
There will be a minimum of 8,100 books with coloured illustrations.
Step-by-step explanation:
Change the percentages to fractions
90% = 9/10
Books with Illustrations: 9/10 of 10,000
Books in Colour: 9/10 of 10,000
Because both events are not mutually exclusive, they can happen at the same time. So multiply their fractions (probabilities).
9/10 * 9/10 =
9 * 9 = 81
10 * 10 = 100
The probability of having a book with coloured illustrations is 81/100.
Find this as a fraction of 10000.
10000 ÷ 100 × 81 = 8,100
