Answer:

Volume of cuboid = 300 in³

Surface area of cuboid = 280 in²

Step-by-step explanation:

Given:

Length = 10 in

Width = 5 in

Height = 6 in

Find:

Volume of cuboid

Surface area of cuboid

Computation:

Volume of cuboid = [L][B][H]

Volume of cuboid = [10][5][6]

Volume of cuboid = 300 in³

Surface area of cuboid = 2[lb][bh][hl]

Surface area of cuboid = 2[(10)(5) + (5)(6) + (6)(10)]

Surface area of cuboid = 2[50 + 30 + 60]

Surface area of cuboid = 2[140]

Surface area of cuboid = 280 in²

RIDDLE ME THIS Fresh and invigorated after completing her algebra homework, Mimi appeared at the living room door. She held a pi
Marat540 [252]

Answer:

Mimi is 15.

Step-by-step explanation:

Set up two equations, and solve by elimination.

 2(m+5) = d+5

- 3(m-5) =  d-5

_____________

2(m+5) - 3(m-5) = 10

2m + 10 - 3m + 15 = 10

-m + 25 = 10

-m = -15

<u>m = 15</u>

Plug this back in to get dad's age.

2(m+5) = d+5

2(15+5) = d + 5

2(20) = d + 5

40 = d + 5

<u>d = 35</u>

<u></u>

14. It costs a pool cover manufacturer $0.15 per square foot for the material they use to make pool covers. If a certain circula
laila [671]

Answer:

$2.83

Step-by-step explanation:

Diameter of the pool = 24ft

Cost of 1 ft² = $0.15

Area of the pool=?

But the pool is a circular pool,

Area of a circle = Πr² or πd²/4

π = 3.142

Area of the pool = (π * 24) / 4

Area = (3.142 * 24) / 4

Area = 18.85ft²

If 1ft² = $0.15

18.85 = $x

x = (18.85 * 0.15) / 1

x = $2.8275 = $2.83

The cost of the pool is $2.83
