The volume of a triangular prism is 90 cubic units, If a triangular prism with a height of 10, length of 6 and width of 3.
Step-by-step explanation:
The given is,
Let, h - Height of the triangular prism
l - Length of the triangular prism
w - Width of the triangular prism
Step:1
Assume, Unit for height, length and width.
From given, ( consider unit)
h - 10 units
l - 6 units
w - 3 units
Step:2
Formula for volume of triangular prism is,
Substitute the values of w,h and l
= (
) × 3 × 10 × 6
= 90
V = 90 cubic units
Result:
The volume of a triangular prism is 90 cubic units, for the given triangular prism with a height of 10, length of 6 and width of 3.
To determine the probability that exactly two of the five marbles are blue, we will use the rule of multiplication.
Let event A = the event that the first marble drawn is blue; and let B = the event that the second marble drawn is blue.
To start, it is given that there are 50 marbles, 20 of them are blue. Therefore, P(A) = 20/50
After the first selection, there are 49 marbles left, 19 of them are blue. Therefore, P(A|B) = 19/49
Based on the rule of multiplication:P(A ∩ B) = P(A)*P(A|B)P(A ∩ B) = (20/50) (19/49)P(A ∩ B) = 380/2450P(A ∩ B) = 38/245 or 15.51%
The probability that there will be two blue marbles among the five drawn marbles is 38/245 or 15.51%
We got the 15.51% by dividing 38 by 245. The quotient will be 0.1551. We then multiplied it by 100% resulting to 15.51%
Here you go!! Hope this helps
Answer:
688 cm²
Explanation:
Area of triangular prism = Base × Height + Length × (perimeter of base)
Here given:
- Perimeter of Base: (6 + 12.4 + 12.4) = 30.8 cm
============================================
Surface Area = 6 × 12 + 20 × (30.8) = 688 cm²
