Answer:
B
Step-by-step explanation:
The volume (V) is calculated as
V = area of triangular face × depth
Area of triangle =
bh ( b is the base and h the height )
Here b = 3 and h = 4 , then
A =
× 3 × 4 = 6 Km²
Now depth = 2, thus
V = 6 × 2 = 12 Km³ → B
Answer:
the answer is 5.6
Step-by-step explanation:
<u>Answer:</u>
The correct answer option is D. 5.
<u>Step-by-step explanation:</u>
We are given the following expression where 4 is to be divided by a fraction 1/5:
÷ 
This can also be written as:

Now to find the quotient of this, we will take the reciprocal of the fraction in the denominator to change it into multiplication.

Therefore, ignoring the 1 in denominator, we can simply multiply 4 by 5.
