Answer:
total surface area = 76 sq.cm
Step-by-step explanation:
total surface area of cuboid = 2 ( lb + lh + bh )
( where l is length , b is width and h is height )
so, surface area :
= 2[ (5×4) + (5×2) + (2×4) ]
= 2 [ 20 + 10 + 8 ]
= 2 × 38
= 76 sq.cm
(5,-2) because when plugging it in the x and y value, those are the only one that actually works.
Is it x times 2 times y times 2? is that what it is asking or is it meaning squared
There would be one donut left. 3-2=1
