I am pretty sure that if you are looking for perimeter there should only be two sets of numbers but if you are looking for area than the answer would be 212.0625

Answer:

218 square feet will be painted.

Step-by-step explanation:

A cement block is in the shape of a rectangular prism that measures 4.5 feet by 7.25 feet by 6.5 feet.

Rectangular prism is a cuboid shape. We have to find the total surface area of cuboid.

Formula:

\text{Total surface area}=2(lb+bh+lh)

where, l=4.5 feet, b=7.25 feet and h=6.5 feet .

\text{Total surface area}=2(4.5\times 7.25+7.25\times 6.5 +6.5\times 4.5)

\text{Total surface area}=218\text{ ft}^2

We will paint entire block of cement i.e must be equal to 218 square feet.

Hence, 218 square feet will be painted.

Please help me with this question!!
quester [9]

Answer:

Step-by-step explanation:

a1 = 6

a2 = 10

a3 = 14

The next member of the sequence is 4 more than the current sequence. Therefore d = 4

a1 = 6

d = 4

n = 13

an = a1 + (n - 1)*d

an = 6 + (n - 1)*4

a_13 = 6 + 12*4

a_13 = 6 + 48

a_13 = 54
