Apublic library has an aquarium in the shape of a rectangular prism. the base is 6 feet by 2.5 feet. the height is 4 feet. how many square feet of glass were used to build the aquarium? the top is open. the answer is 83, but i need the formula

6 * 2.5 = 15 That’s the area of the base

2.5 * 4 = 10
10 * 2 = 20
That’s the area of the 2 smaller sides

6 * 4 = 24
24 * 2 = 48
That’s the area of the 2 larger sides

Then you add all the dimensions together.

15+20+48 = 83.

So, the final equation is (6*2.5) + 2(2.5*4) + 2(6*4) = 83

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form
