Calculate the surface area and volume of this rectangular solid (will give brainliest if correct)

SA = 416, V= 480

Step-by-step explanation:

SA = 2 x 10 x 12 + 2 x 4 x 12 + 2 x 4 x 10 = 416

There are 3 pairs of rectangles of different dimensions that make up the solid thus u just need to find the area of each of the 3 pairs and add them up.

vol = L x B x H = 12 x 10 x 4 = 480

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
