Find the total surface area of a rectangular prism whose width is 8 inches, length is 12 inches and height is 5 inches. Please s
ketch and show work explain I really need your help. URGENTLY PLZ HELP.
1 answer:
The total surface area is going to be the area of all sides added together.
In a rectangular prism there are six sides but the good news is they come in pairs meaning you only have to find the area of three sides.
To find the area of a side multiply its side lengths by each other.
After you found the area of three sides multiply each one by 2.
Then take the three numbers you get from that, add em all up, and there’s your answer!!

Answer:
320 ft²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h (a + b)
where h is the perpendicular height and a, b are the parallel bases
Here h = 16, a = 18 and b = 12 , thus
A = × 16 × (18 + 12) = 8 × 40 = 320 ft²
