The volume of the prism:
V = L x W x H,
where L is the length, W the width and H the height.
We can find the volume of the entire figure by adding together the volumes of two smaller figures ( 2 prisms ).
The 1st one has dimensions: 2, 2, 7 and the 2nd has dimensions 2, 3, 8.
Answer:
B . ( 2 x 2 x 7 ) + ( 2 x 3 x 8 )

Here is a balanced hangar. A circle has a mass of 3 grams and a square has a mass of 2 grams. Which is the mass of a triangle? 3

mrs_skeptik [129]

Answer:

Step-by-step explanation:

Givens

Circle: 3 grams Number: 1 right hand side Number LHS: 2

Square: 2 grams Number: 2 Number LHS: 5

Triangle: x Number: 5 Number LHS: 2

Formula

Mass RHS = Mass LHS

Solution

3*1 + 2*2 + 5x = 3*2 + 5*2 + 2*x Combine

3 + 2 + 5x = 6 + 10 + 2x

5 + 5x = 16 + 2x Subtract 5 from both sides

5-5+5x = 16-5 + 2x Combine

5x = 11 + 2x Subtract 2x from both sides

3x = 11 Divide by 3

x = 11/3

As you can see, I'm not getting any of the answers that you have provided. Ask your teacher how it was done. (The method used is correct).
