Area of a square is l x w=9x9=81
Area of a triangle is 1/2(bxh)=1/2(9x7)=31.5
As there r 4 triangles, multiply 31.5 by 4 to get the tot surface area of the triangles as 126.
Now add the square area to the triangles area for the total surface area.
126+81=207
D is the answer

Base of a prism is a right triangle with legs 3 feet and 4 feet. The height is 13 feet , what is the volume?

julsineya [31]

Answer:

Triangular prisms

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h

Plz explain step by step

kirill115 [55]

Step-by-step explanation:

a=20⁰ vertically opposite angles are equal

b=160⁰ sum of angles on a straight line add up to 180⁰

(180⁰-20⁰=60⁰)

c=125⁰ sum of angles on a straight line add up to 180⁰

(180⁰-35⁰-20⁰=125⁰)
