lawyer [7]

Answer:

Volume = 150 yd^3

Surface Area = 150 yd^2

Step-by-step explanation:

Going by the dimensions of the given three-dimensional figure, we can conclude that the figure is that of a cube. The height, length and width are equal.

Volume of a cube is given as a^3 , while surface area of a cube is given as 6a^2

Where, a = the side length = 5 yards

Volume = a^3 = 5^3

Volume = 150 yd^3

Surface Area = 6a^2 = 6(5)^2

Surface Area = 150 yd^2

trapecia [35]

Answer:

There are 5 cats and 6 children

Step-by-step explanation:

Let x = number of cats

Let y= number of children

Counting heads gives 11

X+Y = 11 .....eq1

Counting feet gives 32

Cats has 4legs,child has 2 legs

4X + 2Y=32 ....eq2

X = 11 - Y

Put in eq2

4(11-Y) + 2Y = 32

44 - 4Y + 2Y=32

12=2Y

Y=12/2=6

Y=6= Children

Put Y=6 in eq2

X + 6=11

X=11-6=5

X= 5 = cats
