For this case we have that by definition, the volume of a parallelepiped is given by:
Where:
l: It's the long
w: It is the width
h: It's the height
From the figure we have the following data:
We must find the value of the length of the parallelepiped:
Answer:
Answer:
and
Step-by-step explanation:
(a)
A = × 4
×
= 2 ×
= ×
← rationalise the denominator
= units²
(b)
Using Pythagoras' identity in the right triangle
let hypotenuse be h , then
h² = (4 )² + (
)²
= 32 +
= +
= ( take the square root of both sides )
h = =
×
← rationalise the denominator
h =
