What is the surface area of the rectangular prism

The answer is 432

Step-by-step explanation:

6 x 8 x 9 =432

348 in^2

Step-by-step explanation:

First you find the surface area for each face

The sides is 8*6

The front and back is 8*9

The top and bottom is 6*9

You then double each number of each face since there is 2 sides of each

8*6=48 * 2 = 96

8*9=72 * 2 = 144

6*9=54 * 2 = 108

Then you all them all together

96 + 144 + 108 = 348

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
