A rectangular prism with a length of 6 ft, a width of 5 feet and a height of 3 feet. Find the Surface Area. Formulas:

A=s2 A = bh A = 12h(b1+b2) A= lw A=12bh
SA = s2 +4(12bh)
SA = 2Lw + 2wh + 2Lh

Step-by-step explanation:

Option 4 is correct.i.e, ( 256 - ) sq. inch

Step-by-step explanation:

Given : A Square is circumscribed about a circle.

           Radius of Circle = 8 inch.

To find : Area of region inside the square but outside of circle.

From Given figure, we have side of square = Diameter of circle

                                                                        = 2 × 8 = 16 inch.

∴ Area of Required region = Area of Square - Area of circle

                                            = side × side -

                                            = 16 × 16 -

                                            = ( 256 - ) sq. inch

Therefore, Option 4 is correct.
