Step-by-step explanation:
(a) What is the area of the base of the box? Use appropriate units.
A=lw
A=8(4)
A=32 inches
(b) What is the volume of the box? Use appropriate units. How can
you use your answer to part (a) to determine the volume?
V=lwh
V=8(4)(5)
V=160 inches
Answer:
2 hours and 15 minutes
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the edge of the cube be a .
Given
Volume V = a³
= 3a² x 2
= 6a²
If a = 40 cm
= 9600 cm³/s .
First, calculate the area of the square, which is 25
next, find the area of one half of the triangle by multiplying 2.5 and 4 (10), then dividing that by 2 (5).
since the two half’s of the triangle are symmetrical, just add 5 and 5 to get 10.
add the area of the triangle (10) and the square (25) to get the total area.
the answer should be 35
hope this helps!
