Answer:
336in^3
Step-by-step explanation:
The volume of a rectangulur prism can be found by multiplying the length of the box with its height and width.
Thus, we can find the volume using the solution below:
v=l*w*h
l = 12in
h = 7in
w = 4in
12*7*4 = 336in^3
Answer:
15 inches
Step-by-step explanation:
The longest side of the right triangular window frame is 39 inches
The height is 36 inches
Let the base of the window frame be x inches
So according to Pythagoras theorem,
x² + 36² = 39²
x² = 39² - 36² = 225
x = 
= 15 inches
The third side of the window frame is therefore equal to 15 inches.
Answer:
<u>1,216 cm³</u>
Step-by-step explanation:
Volume (composite space figure) = Volume (pyramid) + volume (prism)
- ⇒ [16 x 6 x 14 / 3] + [16 x 6 x 8]
- ⇒ 96 [14/3 + 8]
- ⇒ 96 [14/3 + 24/3]
- ⇒ 96 x 38/3
- ⇒ 32 x 38
- ⇒ <u>1,216 cm³</u>
Answer = 7x(4x-1) . Hope it helps.
The equation used to find the surface area of a sphere is 4 x pi x r^2. The surface area of the sphere with a diameter of 16 inches would be
4 x 3.14 x 8^2 = 803.84. Therefore, the surface area of a sphere with a diameter of 16 inches would be 804 square inches. (rounded the decimal)
