What is the surface area of the prism in square feet?
frutty [35]

The surface area of the rectangular prism is 52 square feet (ft^{2}), if the height is 4 feet, width is 3 feet and depth is 2 feet.

Step-by-step explanation:

          The given is,

                    A rectangular prism of

                     Let, h - height of the rectangular prism

                            w - Width of the rectangular prism

                            d - Depth of the rectangular prism

Step:1

        From given,

                     h = 4 feet

                     w = 3 feet

                     d = 2 feet

Step:2

        Formula to calculate the surface area of the rectangular prism is,

                      A = 2 (wd+hd+hw)

       Substitute the values of w,d and h

                           = 2 [(3×2) + (4×2) + (4×3)]

                           = 2 (6+8+12)

                           = 2 × 26

                           = 52

                       A = 52 Square feet

Result:

        Thus the surface area of the rectangular prism is 52 square feet (ft^{2}), if the height is 4 feet, width is 3 feet and depth is 2 feet.

When CPI data is collected, what does the index value represent?
gladu [14]

Answer:

When CPI data is collected, what does the index value represent. Prices used to compute CPI are collected during the entire month, and that data is published monthly. So, the index value represents an estimate of the price level for the month as a whole, rather than a specific date.
