Plz do because I have been struggling with this homework

  1332 m³

Step-by-step explanation:

The volume of a prism is the product of its length (12 m) and the area of its base. This base is a ∩ - shape whose overall dimensions are 11 m high and 15 m wide. The "tunnel" is shown as 6 m high, but we need to calculate how wide it is.

The two "legs" are each 3 m wide, so total 6 m in width. Then the width of the "tunnel" is the difference between that and the overall width of 15 m:

  tunnel width = 15 m -6 m = 9 m

__

One way to compute the base area is to subtract the tunnel area from the overall area:

  base area = B = (15 m)(11 m) -(9 m)(6 m) = 165 m² -54 m² = 111 m²

The volume of the prism is ...

  V = Bl = (111 m²)(12 m) = 1332 m³

The volume of the prism is 1332 m³.

(-1,-0.5)

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
