Answer:
Step-by-step explanation:
Find the area of the base
The base is a square.
The formula is Area = s^2
s = 1.5
Area = 1.5^2
Area = 2.25 sq cm.
Area of 1 triangle
h = 2.4
b = 1.5
Area = 1/2 * b * h
Area = 1/2 * 1.5 * 2.4
Area = 1.8 cm^2
Area of 4 triangles
Area = 4 * area of 1 triangle
Area = 4 * 1.8
Area = 7.2
Total Area = 2.25 + 7.2 = 9.45 cm^2
we are given
climbing rate =4m/s
after 3 second ,
he climbed =4*3=12m
and
he was 13 meters below the edge of the volcano
so, total distance is 12+13=25m
so, distance of the edge of the volcano when he started climbing is 25m.....Answer
speed=4m/s
time = distance / speed
time =25/4
time is 6.25sec......Answer
