Answer:

Step-by-step explanation:

Formula

Volume = L * w * h

Givens

L = 7 feet

w = 4 feet

h = 5 feet

Solution

V = L * w * h Substitute values into the formula

V = 7 * 4 * 5

V = 140 cubic feet.

Answer:

D) 140 cubic feet

Step-by-step explanation:

The given information is,

→ Length (l) = 7 ft

→ Breadth (b) = 4 ft

→ Height (h) = 5 ft

Formula we use,

→ Volume of cuboid = l × b × h

Let's solve the problem,

→ l × b × h

→ 7 × 4 × 5

→ [ 140 ft³ ]

Hence, the volume is 140 ft³.

Need help with 14 and 2 ASAP

Let's start with 14, shall we? Alright, so we know that positive and negative numbers are both on opposite sides of zero- negatives on the left, positives on the right. We see that we have a positive and negative. That lets us know that we have these two values on opposite sides. As for one, we see that it's (going to assume it's negative, as that's what it looks like. If not, do the same thing on the other side.) 5/8, we can only do fourths here, it seems, because there are four intervals between the numbers. Here's where the beauty of equivalent fractions comes in. 5/8 actually equals 2.5/4 if you divide the top and bottom by 2. Now it should be easy to graph it. A little after 1, and then in between 2 and three. Hope this helps.

Answer: the area of a figure is 85.13 in²

Step-by-step explanation:

The area of a figure S consists of the area of a semicircle S₁ and the area of a parallelogram S₂

$\displaystyle\\S_1=\frac{\pi D^2}{4*2} \\\\S_1=\frac{\pi (8)^2}{8} \\\\S_1=\frac{64\pi }{8} \\\\S_1=8\pi \\\\S_1\approx25.13\ in^2\\\\S_2=10*6\\\\S_2=60\ in^2\\\\Thus,\\\\S=25.13+60\\\\S=85.13\ in^2$
