Step-by-step explanation:

complementary angles means that both of them together = 90

13y +12 + 20y + 12 = 90

add all y together and numbers together

33y + 24 = 90

solve for y

33y= 66. y= 2

now let's get the measurements of the angles

13(2) + 12= 38

20(2) + 12= 52

. The volume of a cube is 1728 . Find its edge and total surface area

emmasim [6.3K]

Answer:

Edge = 12

Total Surface Area = 72

Step-by-step explanation:

Volume of the cube = 1728

Length of the edge = $\sqrt[3]{1728} = 12$

We know that

TSA (Total Surface Area) = $6 {a}^{2}$

where a = length of edge of cube

So,

TSA of cube = $6 \times 12 = 72$
