The formula for surface area of a rectangular prism is: 2(wl+hl+hw) which then simplifies to the answer of 592 ft squared
Answer:
592 square feet is the surface area of Rita's room
Step-by-step explanation:
Surface area(S) of rectangle is given by:
[tex]S=2(lw+wh+hl)[/tex]
where,
l is the length, w is the width and h is the height of the rectangle.
As per the statement:
Rita's room is in the shape of a rectangular prism
It is 12 feet long, 10 feet wide, and 8 feet high
⇒l = 12 feet , w = 10 feet and h = 8 feet.
Substitute the given values we have;
[tex]S = 2(12 \cdot 10+10 \cdot 8+8 \cdot 12) = 2(120+80+96) = 2(296) = 592 ft^2[/tex]
Therefore, the surface area of Rita's room is, 592 square feet
