learning task 3 visualize and solve the problem aling sol wanted to redesign her old model box with a dimension of 20 cm long 5 cm wide and 4cm wide​

Answer:  400sq. cm of sticker papers  

Step-by-step explanation:

First, we need to solve the lateral area of the wooden box. We can do that by multiplying the sum of the length and width by 2 then multiplying the product by the height. So, 20 + 5 = 25          25 x 2 = 50      50 x 4 = 200                The lateral area is 200sq.cm                                                                                          For the surface area, we need to add the lateral area to the area of the 2 remaining bases. To solve for the bases, we need to multiply the length by the width Then multiply it by 2 (Because there are 2 bases)                                             20 x 5 = 100       100 x 2 = 200                                                                                       So, the area of the 2 bases are 200sq. cm.  Add the area of the 2 bases to the lateral area which is 400sq.cm                                                                             In conclusion, Aling Sol will need 400sq.cm of sticker paper  to cover the old wooden box.
