Answer:
105 mm^3
Step-by-step explanation:
The volume formula for a triangular prism is (height x base x length) / 2. 
(5 x 6 x 7) / 2 = 105 mm cubed = 105 mm^3

Answer:
2520cm²
Step-by-step explanation:
Surface area = sum of the area of all the bases. 
Area of bottom base = 28 * 30 = 840 
Area of right base = 25 * 30 = 750 
Area of left base = 17 * 30 = 510 
Area of two triangles = ( 15 * 28 ) / 2 = 210 * 2 = 420 
Then add all the areas together to find surface area 
Surface area = 840 + 750 + 510 + 420 = 2520cm²
Relevant Formulas: 
Area of a rectangle = length * width. This formula was used to find the area of the bottom base, the right base and the left base
Area of a triangle = ( height * base length ) / 2 . This formula was used to find the area of the sides which are triangles. 
 
        
             
        
        
        
Answer: For number 1 tell Andre no.
Step-by-step explanation: This is because he wants to make a scaled copy of Jada's drawing but by turning 4 into 8 by adding, it will create consistences to the point the best way to scale would be to multiply. So, Tell Andre that if he wants 4 to be 8, he should multiply instead of adding. Very epic!
