Answer: 30
Step-by-step explanation:
Simple formula is
LCM*GCF=PRODUCT OF 2 NUMBERS
120 * 10 = 40 * x
1200 = 40x
x = 1200/40
x = 30
The surface area of a rectangular prism can be found by adding the area of all sides together. To start, we will have to find the dimensions for the new prism, which is 5 * 6 * 8.
Then, we will have to find the area for each side. One of the sides will have 8*6, another 8*5, and the last 5*6.
We will then have 48, 40, and 30. Multiply them all by 2 and add them all together.
You will receive the final answer of 236 square inches.
Option D:
160 plastic cubes can fit into the box.
Solution:
Convert mixed fraction into improper fraction.
Length of the box = 4 ft
Width of the box =
ft
Height of the box = 2 ft
Volume of the box = length × width × height

= 20 ft³
Volume of the box = 20 ft³
Length of the plastic cube =
ft
Volume of the cube = length × length × length

Volume of the cube = 0.125 ft³

= 160
Number of plastic cubes = 160
Hence 160 plastic cubes can fit into the box.
Option D is the correct answer.
