Answer:
the answer is C: 1932 sq. cm
Step-by-step explanation:
You want to break down the sections (which is double for each)
there are 6 rectangles but you will only need to calculate for 3
1st rectangle
a = (25) (12)
a = 300 sq. cm
**then multiply by 2 = 600 sq. cm**
2nd rectangle
a = (12) (18)
a = 216 sq. cm
then 216 * 2 = 432 sq. cm
3rd rectangle
a = (25) (18)
a = 450 sq. cm
then 450 * 2 = 900 sq. cm
Total Surface Area
SA = 600 sq. cm + 432 sq. cm + 900 sq. cm
SA = 1932 sq. cm
Answer:
The surface area of the triangular prism is 84 square centimeters.
Step-by-step explanation:
The surface area of a figure is exactly what it means, the area of its outer surface or the added areas of each face that makes the figure.
Nets are a way to find surface area easier because it is an outline of the faces of the 3d figure.
But since we don’t have a net, we will just find the area of each face that forms this right triangular prism:
The two congruent triangular bases:
1/2 x 4 x 3 = 6 cm^2
6 x 2 = 12 cm^2
Lateral bottom rectangular face:
6 x 3 = 18 cm^2
Lateral to the right rectangular face:
5 x 6 = 30 cm^2
Lateral to the left rectangular face:
4 x 6 = 24 cm^2
Add up all the values:
12 + 18 + 30 + 24 = 84
The SA is 84 square centimeters
Answer:
i belive it was 750.
Step-by-step explanation:
Answer:
75.36 inches
Step-by-step explanation:
C = π·d
C = 3.14(24)
C = 75.36
Answer:
Step-by-step explanation:
x2 - 4x - 12 = 0
x2 - 6x + 2x - 12= 0
x(x - 6) + 2(x - 6) = 0
x + 2 = 0
x = - 2
x - 6 = 0
x = 6
