What is the surface area of the pyramid to the nearest whole number?

256 cm^2
128 cm^2
64 cm^2
192 cm^2

64 cm²

Step-by-step explanation:

To find the area of the square pyramid:

We use the formula;

Area of the square pyramid =   B +  p . l

Where b = area of the base

p = perimeter

l = slant height

Area of base =  length × breadth

                        =  4 cm  ×   4 cm  

                        =  16 cm²

slant height is given as 6 cm

Perimeter =  4 cm + 4 cm + 4 cm + 4 cm = 16 cm

Now we can plug all our variable into the formula;

Area of the square pyramid =   B +  p . l

                                               =16 cm² +  ×  16 cm  × 6 cm

                                                = 16 cm²  +  48 cm²

                                                  =  64 cm²

(   Note; the value of  ×  16 cm  × 6 cm = 48 cm²)

Therefore the surface area of the pyramid is 64 cm²

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
