The volume of a rectangular pyramid = 1/3 ×Area×height
=1/3×L×W×H
if the dimensions were doubled
therefore,
V=1/3 × (9×2)×(14×2)×(10×2)
=1/3×18×28×20
=3360 cubic centimetres

Line m is parallel to line n. The measure of angle 2 is 64°. What is the measure of angle 5?
zloy xaker [14]
Angles 2 and 6 are corresponding angles.
When parallel lines are cut by a transversal, corresponding angles are congruent, so angles 2 and 6 are congruent.
m<2 = m<6 = 64 deg.

Angles 5 and 6 are a linear pair, so they are supplementary, and their measures add to 180 deg.

m<5 + m<6 = 180

m<5 + 64 = 180

m<5 = 180 - 64

m<5 = 116

Answer: m<5 = 116 deg.

A rectangle's perimeter and area have the same value. The width of the rectangle is 6 units. What is the length of the rectangle
Sliva [168]

Answer:

The length ot rectangle is 3 units.

Step-by-step explanation:

The formula for perimeter is P = 2l + 2w and the area is A = l×w. Assuming that the perimeter and area have the same values so you have to compare it :

perimeter = 2l + 2w

area= l \times w

perimeter = area

2l + 2w = lw

let \: w = 6

2l + 2(6) = 6l

2l + 12 = 6l

12 = 6l - 2l

4l = 12

l  = 3 \: units
