Solution:
<u>Note that:</u>
- Surface area: 2(LB) + 2(BH) + 2(LH)
<u>Substitute the values given into the expression to find the surface area.</u>
- 2(7 x 10) + 2(6 x 6) + 2(6 x 10)
- => 2(70) + 2(36) + 2(60)
- => 140 + 72 + 120
- => 332 mm²
The surface area of the rectangular prism is 332 mm².
D because if you use a^2+b^2=c^2 d is the only one that’s false *plug the numbers in*
Answer:
28
Step-by-step explanation:
It helps to plot the points on a graph. It is easy to see that three of the sides are of length 6, and the remaining two are the hypotenuse of a 3-4-5 triangle, hence length 5.
3×6 +2×5 = 28
The perimeter of this polygon is 28 units.
Answer:
