147.64cm²

Step-by-step explanation:

1. It gives you the surface area of the top and bottom of the cuboid. So double 30cm² = 60cm²

2. Volume is area times height. So working backwards from the volume to find height is:

120cm³/30cm²=4cm

3.Now take the sqrt of the base times the height

:

147.64cm²

i know the answer is 3

step-by-step explanation:

yes because there is exactly one y value for every x value
