Answer:
A = 21572
Step-by-step explanation:
<em><u>The formula to find a rectangular prism's area is:</u></em>
A = 2wl + 2lh + 2hw
<em><u>OR</u></em>
A = 2(wl + lh + hw)
<em><u>So plug in the numbers into the formula accordingly:</u></em>
A = 2(47 · 66 + 66 · 68 + 68 · 47)
A = 2(3102 + 4488 + 3196)
A = 2(10786)
A = 21572
Answer:
260°
Step-by-step explanation:
∠RPS +∠PSR +∠SRP= 180° (∠ sum of △PRS)
∠RPS +45° +60°= 180°
∠RPS +105°= 180°
∠RPS= 180° -105°
∠RPS= 75°
Let's focus on quadrilateral PQTU.
Sum of interior angles= (n -2) ×180°, where n is the number of sides
∠QPU
= ∠RPS +∠TPU
= 75° +25°
= 100°
Sum of interior angles= (4 -2) ×180°
m +n +p +100°= 2 ×180°
m +n +p +100°= 360°
m +n +p
= 360° -100°
= 260°
Answer:
264 sq. in.
Step-by-step explanation:
The easiest way to find the lateral surface area is to multiply the perimeter of the base times the height.
In your case the perimeter of the base is 2(8) + 2(3) = 16 + 6 = 22
The height is 12, so multiply 12 times 22 = 264 sq. in.

-2y= -6x+12
-2y= -2 (3x-6) |</span>÷ (-2)
y= 3x-6
