Answer:
0.000003721m
Scientific Notation: 3.72*10^-6
Step-by-step explanation:
1nm is 1*10^-6nm
Based on that we find the answer above.
Area of rectangle = l*w
Area of triangle = (1/2)*l*w
Based on the figure:
Area of triangles = 2*(1/2)*l*w
= 2*(1/2)*24*14 = 336 cm^2
Area of side rectangles = 2*l*w
= 2*44*25 = 2200 cm^2
Area of bottom rectangle = l*w
= 44*14 = 616 cm^2
To find the total surface area, you would add all of the sides together:
336+2200+616= 3152 cm^2
Don’t be afraid to ask any questions, if you have any :D
