A = -2 if you do it all right
Answer:
The surface area of the prism is 8/3ft²
Step-by-step explanation:
To calculate the surface area of the prism we have to use the following formula:
a = area
w = side = 2/3 ft
h = height = 2/3 ft
l = length = 2/3 ft
a = 2 * (w * h) + 2 * (w * l) + 2 * (h * l)
we replace the values that we know
v = 2 * (2/3 ft * 2/3 ft) + 2 * (2/3 ft * 2/3 ft) + 2 * (2/3 ft * 2/3 ft)
v = 2 * 4/9ft² + 2 * 4/9ft² + 2 * 4/9ft²
v = 8/9ft² + 8/9ft² + 8/9ft²
v = 24/9ft²
v = 8/3ft²
The surface area of the prism is 8/3ft²

*Tip: Just move the decimal place over the number of times the exponent is (Ex: 2.54*10^-1, all you have to do is move the decimal place over one time to the left).
*Tip: If the exponent is positive, move it to the right. If it is negative, move it to the left.
Hope I helped! <3
I wrote it out this time, so I didn't forget any work like last time. LOL
