Answer 2

the surface area of the rectangular prism is found as : S = 275 ¹/₈ cm².

Length l = 11 ³/₄ cm = 47/4 cm = 11.75 cm

width w = 5 ³/₄ cm = 23/4 cm = 5.75 cm

height h = 4 cm

surface area of the prism S = 2(lw + wh + hl)

S = 2(11.75*5.75 + 5.75*4 + 4*11.75)

S = 2*137.5625

S = 275.125

S = 275 ¹/₈ cm²
