Question

surface area of a cuboid 4.8cm , 3.1cm,7.2cm

Answer 1

Answer:

143.52 cm

Step-by-step explanation:

To find the surface area of a cuboid, you need to find the area of each side and then add them together.

4.8 times 3.1= 14.88

You would then do 14.88 times 2 because there will be a side with that same area.Which equals 29.76.

3.1 times 7.2= 22.32

You would then do 22.32 times 2. Which is 44.64.

7.2 times 4.8= 34.56

You would then do 34.56 times. Which equals 69.12

Now you do 29.76+44.64+69.12=143.52
