Answer:

The total volume of the solid is 1.67 cubic units.

Step-by-step explanation:

Each pyramid with a height of 2 units and a rectangular base with dimensions of 5 units × 0.25 units.

1/3 x (area of base) x height

= 1/3 x (5 x 0.25) x 2= 0.833

Therefore, the volume of each pyramid will be

= cubic units.

So, the total volume of the solid is (2 × 0.833) = 1.67 cubic units. (Answer)

Answer:

Rectangle 1: 84 ft^2   Rectangle 2: 8 ft^2

Step-by-step explanation:

Split the figure into two rectangles

Rectangle 1:

Width of rectangle 1 can be found by subtracting 8 ft from 15 ft

15-8=7 ft (width)

length is already given as 12 ft

So,

A = L x W

A = 12ft x 7 ft

A = 84 ft^2

Length is already given of one of the rectangles

Rectangle 2:

Finding the width of Rectangle 2 can be found by subtracting 11 ft from 12 ft to find the length of that dashed line or the width of rectangle 2.

12 ft - 11 ft = 1ft (width)

Length: 8 ft

Width: 1ft

A=l x w

A=8 x 1

A=8 ft^2
