35 cm2; 364 cm2
70 cm2; 364 cm2
35 cm2; 266 cm2
70 cm2; 266 cm2

Answer 1

use the formulae for rectangular prism

Answer 2

Lateral Area = perimeter of base * height

Answer 3

perimeter of base = 2(l + b) = 2(7+14) = ?

Answer 4

42

Answer 5

sorry my computer is stupid

Answer 6

Answer 7

lol ok so that the perimeter of base, to get lateral area, u need to multiply it wid height 1.66

Answer 8

sooooo 69.72

Answer 9

round it to nearest whole numebr

Answer 10

70:D

Answer 11

great ! next total surface area

Answer 12

okay how do i find that?

Answer 13

do u knw the formula for surface area of rectangular prism ?

Answer 14

2ab + 2bc + 2ac

Answer 15

that works.

Answer 16

okay lol

Answer 17

or we can use a much simpler formula, as we computed lateral area = 70 already

Answer 18

okay whats that

Answer 19

surface area = lateral area + 2* area of base
= 70 + 2*(7*14)
= ?

Answer 20

266?

Answer 21

right.. ur calculator wont cheat u lol

Answer 22

haha so its d:D

Answer 23

yes
