Answer:

Explanation:

SA = 2B + LA B = area of base LA = lateral area

B = area of the rectangle with length of 9.5 and width of 5

= 9.5(5) = 47.5

LA = perimeter of base times the height

= [2(9.5) + 2(5)] (8)

= (19 + 10)(8)

= 29(8)

= 232

SA = SA = 2B + LA = 2(47.5) + 232

= 95 + 232

= 327 sq cm

Answer:

327 cm²

Explanation:

The opposite faces of a cuboid are congruent , front and back, top and bottom, the two side faces, then

SA = 2(9.5 × 8) + 2(5 × 8) + 2(9.5 × 5)

= (2 ×76) + (2 × 40) + (2 × 47.5)

= 152 + 80 + 95

= 327 cm²
