Answer:
90 cm
Step-by-step explanation:
15 x 6 = 90
first put them in order: 0,0,0,0,0,0,1,1,1,1,1,1,1,2,2,2,2,3,3,3,3,4,4
then make a number like with the numbers 0 1 2 3 4 on it and put the amount of dots there are for that number
for example under 0 would be 6 0's because there are 6 0's
Surface area = 92 ft²
Formula to find the surface area of a rectangular prism is,
Surface area = 2(lb + bh + hl)
Here, l = length of the prism
b = width of the prism
h = height of the prism
By substituting the measures of the sides given in the picture,
Surface area = 2(2×3 + 3×8 + 8×2)
= 2(6 + 24 + 16)
= 2(46)
= 92 square feet
Therefore, surface area of the given rectangular prism is 92 ft².
