The formula Bh (1/2 x b x h x h) is for what?
What is Volume of a triangular prism.
100
A prism with equilateral triangles has a base of 4 and a height of 5. The height of the prism is 5. To find the volume, I did 3 x 3 x 3 x 5 x 1/2 and got 67.5. What mistake did I make? Bonus: What is the correct answer?
What is no, to get the volume it is area of the base x height. Bonus: 1/2 x 4 x 5 x 5 = 50 cubic units

Find the volume of a triangular prism that has an equilateral triangle with a base of 5 and a total height of 4.
What is 45 units cubed.
200
The formula for the surface area of a rectangular prism is SA = 2lw x 2lh x 2wh
What is False The correct formula is SA = 2lw + 2lh + 2wh

The formula pi x r x r x h is for...
What is Volume of a cylinder
200
A cylinder has a diameter of 10 and a height of 3. To get the volume, I did pi x 10 x 3 and got 94.2. Is this correct? What mistake did I make? Bonus: What is the correct answer?
What is No. To get the volume you mutiply pi x radius x radius x height, but I used the diameter. Bonus: pi x 5 x 5 x 3 = 235.5 cubic units

Find the volume of a cylinder with the height of 7 and a diameter of 4.
What is 87.92 units cubed
300
The formula for the surface area of a cylinder is 2(pi)rh + 2(pi)rr
What is True

What do we call the place where three or more faces of an object meet?
What is a vertex.
300
A triangular prism with equilateral triangles has a base of 5 and a height of 7. The height of the prism is 9. To find the surface area, I used (5 x 7) + (5 x 5 x 5)(9). Is this correct? What mistake did I make? Bonus: What is the correct answer?
What is no. I multiplied to find the perimeter instead of adding. Bonus: (5 x 7) + (5 + 5 + 5)(9) = 170 units squared
300
Find the volume of a prism with a length and width of 6 and a height of 7.4
What is 266.4 units cubed
400
What is bh + Pw?
What is the surface area of a triangular prism.
400
2 x pi x r When finding the volume of a cylinder, this part of the formula finds the circumference of the circle. Why do we need to find the circumference?
What is The circumference is equal to the length of the rectangle.
400
A rectangular prism has a length of 4, a width of 7, and a height of 6. To calculate the surface area, I used 2 x 4 x 7 + 2 x 4 x 6 + 2 x 7 x 6 = 58,548 units squared. Is this correct? What mistake did I make? Bonus: What is the correct answer?
What is no. I didn't do the multiplication before the addition. Bonus: (2 x 4 x 7) + (2 x 4 x 6) + (2 x 7 x 6) = (56) + (48) + (84) = 188 units squared.

Find the SA of a triangular prism with a base of 4, a height of 6, and a width of 18.
What is 1320 units squared

What is 6lw?
What is the surface area of a cube.
500
What is Bh?
What is the volume formula for any 3-dimensional object.
500
A cylinder has a radius of 5 and a height of 7. To find the surface area, I used 2 x pi x 5 x 7 + 2 x pi x r x 2. Is this correct? What mistake did I make? Bonus: What is the correct answer?
What is no. Instead of squaring the radius, I multiplied it by 2. Bonus: 2 x pi x 5 x 7 + 2 x pi x 5 x 5 = 376.8 units squared.
500
A cylinder has a radius of 2 and a height of 15. The rectangle of the cylinder has a length of 12.56. What is the surface area of the cylinder?
What is 213.52
