The total surface area is the sum of the lateral area and the area of the bases.
The area of each triangular base is
A = (1/2)bh
A = (1/2)(8 in)(3 in) = 12 in²
The lateral area is the product of the perimeter of the base and the distance between bases.
A = Ph
A = (5 in +5 in +8 in)(12 in) = 216 in²
Then the total area is
2*base area + lateral area
= 2(12 in²) +(216 in²)
= 240 in²
The surface area of the prism is 240 in².
Using a calculator divide 2x10^8 by 5x10^6 and you get 40 therefore it is 40 times larger
Answer:
$21.00
Step-by-step explanation:
1(x+3)+x=45
x+3+x=45
x+x=42
2x=42
x=21
Answer:
(1,33,38)
Step-by-step explanation:
got right on edg
15 = 80% * x
15 = 80/100 * x
15 = 8/10 * x
x = 15 * 10/8
x = 150/8
x = 18.75
