Corrected Question
The triangular prism shown has 1, 2, 3 or 5 triangular faces and 1,2,3, or 5 lateral faces.
The area of one triangular face is 7.5,8.125,15,or 17
The surface area of the triangular prism is 55.5,127.5,135,or 150
Answer:
(B)2 triangular faces
(C)3 lateral faces.
(A)Area of one Triangular Face
(C)Total Surface Area of the Triangular prism
Step-by-step explanation:
The triangular prism is attached.
The triangular prism shown has 2 triangular faces and 3 lateral faces.
Base of the triangle =2.5mm
Height of the Triangle =6mm
Area of one Triangular Face
The dimensions of the lateral rectangles are:
- 2.5 mm by 8mm
- 6 mm by 8mm
- 6.5 mm by 8mm
Therefore, total surface area of the triangular prism
=2(Area of one Triangular Face)+Area of 3 rectangular faces
Total Surface Area of the Triangular prism
Answer:
0.2
Step-by-step explanation:
Given:
Total number of students = 20
Number of students who have brown hair = 12
Number of students who have blonde hair = 4
Number of students who have red hair = 3
Number of students who have black hair = 1
To find:
Probability of randomly selecting a blonde-haired student from the classroom.
Solution:
Probability refers to chances of occurring of some event.
Probability = Number of favourable outcomes/ Total number of outcomes
Number of favourable outcomes ( Number of students who have blonde hair ) = 4
Total number of outcomes = 20
So,
Probability of randomly selecting a blonde haired student from the classroom =
