Question 4 • Mathematical Models with Applications - MA4072 CR
Use the rectangular prism surface area formula: 2(lw + lh + wh). With length 4 cm, width 2 cm, and height 3 cm, the three face-area products are 4 × 2 = 8, 4 × 3 = 12, and 2 × 3 = 6. Thus, the surface area is 2(8 + 12 + 6) = 52 square centimeters, so the correct choice is 52 sq. cm.
