Question

What is the surface area of this rectangular prism i-ready

Answer 1

Answer:

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

Step-by-step explanation:

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

$2 \times (lenght) \times (widht) + 2 \times (lenght) \times (height) + 2 \times (widht) \times (height)$

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

$2 \times 5 \times 5 + 2 \times 5 \times 12 + 2 \times 5 \times 12$

Simplify each term.

$50 + 120 + 120$

Simplify by adding numbers.

$290(in)^{2}$

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

Answer 2

Answer:

290 in²

Step-by-step 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
