The total surface area of the cuboid is 143.52 cubic cm
<h3>Surface area of a cuboid</h3>
The formula for calculating the surface area of a cuboid is expressed as:
SA = 2(lw + wh + lh)
where
l is the length = 7.2cm
w is the width = 3.1cm
h is the height = 4.8cm
Substitute
SA = 2(7.2*3.1 + 7.2*4.8 + 3.1*4.8)
SA = 2(22.32 + 34.56 + 14.88)
SA= 143.52 square cm
Hence the total surface area of the cuboid is 143.52 cubic cm
