Use the formula SA equals 2 left parenthesis small script letter l w right parenthesis plus 2 left parenthesis wh right parenthesis plus 2 left parenthesis small script letter l h right parenthesis to find the surface area for a rectangular prism with the length small script letter l of 2.9 cm​, a width w of 1.12 cm​, and a height h of 7 cm.

Respuesta :

Sure, let's use the formula for the surface area (SA) of a rectangular prism:

SA = 2lw + 2wh + 2lh

Given:
Length (l) = 2.9 cm
Width (w) = 1.12 cm
Height (h) = 7 cm

Plug in the values:

SA = 2(2.9)(1.12) + 2(1.12)(7) + 2(2.9)(7)

Calculate each term:

SA = 2(3.248) + 2(7.84) + 2(20.3)
= 6.496 + 15.68 + 40.6
= 62.776 cm²

So, the surface area of the rectangular prism is 62.776 square centimeters.
