A carpenter constructed a rectangular sandbox with a capacity of 10 cubic feet. If the carpenter were to make a similar sandbox

jeka57 [31]

Answer:

(D)80 ft³

Step-by-step explanation:

The volume volume of the sandbox is = L × W × H

Where L = Length, W= width, H= Height.

A sandbox has the same shape as a cuboid.

A cuboid is a solid shape with rectangular base and sides. It has six rectangular faces if all sides are closed.

From the question,

LWH = 10ft³ ........................ (1).

If a similar sandbox twice as long, twice as wide and twice as high.

∴ L₍n₎= 2L, W₍n) =2W, H₍n₎ = 2H

Where L₍n₎, W₍n), H₍n₎ is the new Length, new Width and new Height of the similar sandbox.

∴L₍n₎ ×W₍n)× H₍n₎ = 2L × 2W × 2H

and Volume of the new sandbox = L₍n₎ ×W₍n)× H₍n₎

⇒Volume of the new sandbox = 2 × 2 ×2 ×L×W×H

Volume of the new sandbox = 8 × LWH....................(2)

In equation(1) LWH = 10ft³.

Substituting the value in equation(2)

∴Volume of the new(similar) sandbox= 8 × 10

=80ft³.

Therefore the capacity of the second sandbox in cubic feet is 80.

The answer is option (D).

Dario bakes a lasagna containing $\frac 23$ pound of parmesan cheese, $1\frac 14$ pounds of ricotta cheese, and $1\frac 13$ poun

svp [43]

Answer: There are 13 slices when Dario cuts .

Explanation :

Since we have given that

Quantity of parmesan cheese is given by

$\frac{2}{3}$

Quantity of ricotta cheese is given by

$1\frac{1}{4}$

Quantity of mozzarella cheese is given by

$1\frac{1}{3}$

Now, total quantity of cheese Dario have

$\frac{2}{3}+\frac{5}{4}+\frac{4}{3}=2+\frac{5}{4}=\frac{8+5}{4}=\frac{13}{4}$

Now,

According to question, Dario cuts the lasagna into several equal slices and each containing exactly

$\frac{1}{4}\ pounds\ of\ cheese$

So,

Number of slices is given by

$\frac{\frac{13}{4}}{\frac{1}{4}}=13$

Hence, there are 13 slices when Dario cuts .
