Answer:

The surface area of the prism is 8/3ft²

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
