Surface Area of a Rectangular Prism
To find the surface area of a rectangular prism, we can use the following formula:
[tex]SA=2(lw+lh+wh)[/tex]
- l = length
- w = width
- h = height
Solving the Question
We're given:
- l = 4 yards
- w = 1 yard
- h = 3 yards
Plug the given measurements into the formula for surface area:
[tex]SA=2(lw+lh+wh)\\SA=2[(4)(1)+(4)(3)+(1)(3)]\\SA=2(4+12+3)\\SA=2(19)\\SA=38[/tex]
Therefore, the surface area of the rectangular prism is 38 yd².
Answer
38 square yards
