Answer:
Step-by-step explanation:
Given that each question after the first is worth 4 points more than the preceding question.
Total questions = 10
Let a be the marks for the first question.
Then the marks for 10 questions in order are a, a+4, a+8,....a+36
This is an arithmetic sequence with common difference d =4
Sum of 10 terms =
This sum is given as 360
Equating we get
Hence III question will have points as 18+2(4) = 26.

Step-by-step explanation:
A prism is a three dimensional shape with two identical shapes facing each other known as bases.
A triangular prism has two triangular bases and three rectangle.
From the net attached:
Area of triangle 1 = area of triangle 2 = (1/2) * base * height = (1/2) * 10 cm * 12 cm = 60 cm²
Area of rectangle 1 = Area of rectangle 2 = length * width = 13 cm * 7 cm = 91 cm²
Area of rectangle 3 = base * height = 10 cm * 7 cm = 70 cm²
Total surface area = Area of triangle 1 + Area of triangle 2 + Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3
Total surface area = 60 + 60 + 91 + 91 + 70 = 372 cm²
