I need help with the prisms and surface area practice
on questions 1-5.
I can't do the copy and paste thingy and it's geometry in which I'm bad at
Sure, I can definitely help you with that! Can you please manually type out the questions and give me more details about what specifically you're having trouble with?
use the formula S=2(lw)+2(wh)+2(lh)
now just plug in your numbers!
No worries! I can still help you with understanding how to solve the prism and surface area questions without the need for copying and pasting. Geometry can be challenging, but I'll do my best to explain the concepts to you. Let's start by understanding what a prism is.
A prism is a three-dimensional shape with two parallel congruent bases and rectangular or triangular faces connecting the bases. The surface area of a prism can be found by calculating the sum of the areas of all its faces.
Now, let's move on to the practice questions. Since you mentioned there are five questions, I'll walk you through the steps to solve the first question. Then, you can follow the same process for the remaining questions.
Question 1: Find the surface area of a rectangular prism with a length of 6 units, width of 4 units, and height of 3 units.
To find the surface area of the rectangular prism, we need to calculate the areas of each face and then sum them up.
1. The top and bottom faces (bases) of the prism are rectangles. The area of a rectangle is found by multiplying the length and width. So, the area of each base in this case is 6 units x 4 units = 24 square units.
2. The front and back faces of the prism are also rectangles with a length of 6 units and a height of 3 units. Therefore, the area of each rectangle is 6 units x 3 units = 18 square units.
3. The remaining two faces on the sides of the prism have a width of 4 units and a height of 3 units. So, their areas are also 4 units x 3 units = 12 square units each.
4. Finally, to find the total surface area, we add up the areas of all the faces: 2(24 square units) + 2(18 square units) + 2(12 square units) = 48 square units + 36 square units + 24 square units = 108 square units.
Now that you understand the process for question 1, you can apply the same steps to solve the remaining questions on the prism and surface area practice.
Let me know if you need further assistance or if you have any other questions!
i can try
1. use the formula S=2(lw)+2(wh) to find the surface area of a rectangular prism with the follow demensions
.length = 2cm
.width = 3cm
.height = 4cm
A. S=21cm/2
B. S=48cm/2
C. S=52cm/2
D. S=96cm/2
