What is the volume of the square pyramid with base edges 4 m and height 3 m
olya-2409 [2.1K]

16 m³

Step-by-step explanation:

Step 1:

Here we are going to find the volume of square pyramid.

Volume of square pyramid = (1/3) × (Base)^{2} × (Height)

Here base = 4 m

         Height = 3 m

Step 2:

Volume = (1/3) × (4 × 4) × 3

              = 16 m³

Use the exterior angle theorem to find the value of x in the triangle below.
Arisa [49]

Answer:

Option A

Step-by-step explanation:

By using the definition of an exterior angle of a triangle,

"Measure of the exterior angle of a triangle is equal to the sum of measures of the opposite interior angles"

m∠STP = m∠SWT + m∠STW

Substitute the measures of the angles from the picture attached,

15x = (7x + 1) + (7x + 6)

15x = (7x + 7x) + (1 + 6)

15x = 14x + 7

15x - 14x = 7

x = 7

Therefore, Option A will be the correct option.

Can someone help me
Deffense [45]

Answer:

w = 10 cm

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = \frac{1}{2} base × height

here base = 6 and height = 8, thus

A = 0.5 × 6 × 8 = 3 × 8 = 24 cm²

The area of the rectangle = 5 × 24 = 120 cm²

area of rectangle = lw ( l is length, w is width )

Here l = 12, thus

120 = 12w ( divide both sides by 12 )

w = 10 cm
