Answer:

The surface area of this prism is 290(in)²

Explanation:

The surface area of a box is equal to the sum of the areas of each side of the box.


2 * (lenght) * (widht) + 2 * (lenght) * (height) + 2 * (widht) * (height)

Substitute the values of the length l=5, the width w=5, and the height h=12 into the formula.


2 * 5 * 5 + 2 * 5 * 12 + 2 * 5 * 12

Simplify each term.


50 + 120 + 120

Simplify by adding numbers.


290(in)^(2)

Hence, The surface area of this rectangular prism is 290in².

Answer:

290 in²

Explanation:

Using the net of the box given, we can see that there are 4 equal rectangles and 2 equal squares that make up the prism.

Area of the 4 rectangles = 4(60) = 240 in²

Area of the 2 squares = 2(25) = 50 in²

Therefore,

Surface Area of the prism = 240 + 50 = 290 in²
