Plz just me, i had a really bad day already, so just with these simple question. i will give brainliest if correct. and a ! you. : ) 50 points for five questions. each question has one picture.

1. what is the volume of this triangular prism?

182^3
195 ^3
210 ^3
390 ^3

2. which equation can be used to find the volume of this solid?

v= 2*4*5
v= 2+5+4
v= 2*5
v= 4*5

3. a box at the post office has dimensions as shown below.

what is the volume of the box?
1,304 ^3
1,536 ^3
1,636 ^3
2,304 ^3

4. how much cubic space is in matti’s greenhouse?

220.5 ft^3
367.5 ft^3
472.5 ft^3
735.0 ft^3

5. what is the volume of the right triangular prism? round to the nearest tenth.

30.7m^3
61.4m^3
306.9m^3
613.8m^3

1. Let us find volume of our right triangular prism.

Since we know that volume of a triangular prism equals to area of base times height of prism.

, where b is area of base and h is height of prism.

Therefore, volume of our triangular prism is 195 cubic meters and option B is the correct choice.

2. Let us find equation for volume of our given cuboid.

Therefore, our equation will be and option A is the correct choice.

3. Let us find volume of box (cuboid) at the post office.

Therefore, volume of box will be 1536 cubic inches and option B is the correct choice.

4. Let us find volume of Matti's greenhouse, which is a triangular prism.

Since we know that volume of a triangular prism equals to area of base times height of prism.

Therefore, volume of Matti's green house will be 367.5 cubic feet and option B is the correct choice.              

5. Let us find volume of our right triangular prism.

Since we know that volume of a triangular prism equals to area of base times height of prism.  

Therefore, volume of our right triangular prism will be 306.9 cubic meters and option C is the correct choice.  

b. f(x) = –√x + 3this is the correct answer
